Sweet Dog Suddenly Gets Aggressive Towards Owners



We have a pit mix his name is Diesel. He gets along with our 2 year old blood hound. Never got along with other dogs. Never bothered us. He barks when people are at the door until he gets to know them.

But within the past week, he has been growling when you put ur face near his which has never ever been an issue. He's a big cuddler and always has been.

But today I opened the door to say bye before work dropped right to my knee and put my face right next to his and started to pet him he started to growl very loud and then nipped at me. So I gave him a little smack and then went to pet him again and he bit my hand really bad broke blood on top and bottom.

Believe me he has never ever been aggressive towards me or other people he's the sweetest dog I know. And I may have been a little rough to him but no rougher than I've ever been when he did that. But when my girl friend pets him he's growling and when I pet him he makes a very loud aggressive sounding open mouth growl and tucks his ears back looking ready to attack.

My girlfriend is getting scared of him and talking about bringing him to a pound she's so worried. We love this dog. He's our baby and we don't ever wanna lose him so we are very worried about this cause we don't wanna be scared of our own dog...

Please tell us what we can do other than training that we can't afford.

Gale's Reply:

Your first step should be to take Diesel to the vet and have him thoroughly checked to rule out any medical problems. Sudden behavioral changes like this can be the first sign that something is wrong physically. It turns out to be the case more often than you might think.

Don't skip over this. Diesel may look fine. But, if there is an underlying medical condition that isn't addressed, his behavior will not improve no matter what you do. And, you may lose the advantage of early detection and treatment if there is an advancing illness.

Once he is cleared medically, consider his age. At two years old, he is just coming into full social maturation as an adult dog. Sexual maturation happens earlier. But as social creatures, pits usually reach their adulthood between 14 and 36 months.

My point about that is this. A lot of dogs don't like
it when you get in their face. Neither do they like being hugged around the neck the way we humans tend to do it. To us it's a gesture of affection. But, to a dog it can feel like a threat or a challenge. Perhaps Diesel is one of those dogs who tolerated it or even enjoyed it as a puppy, but doesn't like it as a dog.

You mentioned that when Diesel growls, his ears go back. That's not an aggressive stance, it's generally a fear response. To me, this reinforces the importance of having him checked by the vet to make sure he's not in pain or anticipating pain from your touch.

It also begs the question as to whether Diesel has become afraid of you. If you regularly use physical force to punish him, there's a good possibility that this is the case. And, if so, you'll need to work to regain his trust.

As I read your description of the incident above, I can't help but wonder if you are viewing Diesel's growl as a challenge to your authority rather than simply his attempt to communicate something in the only way he knows how. You really need to step back from reading too much into his behavior.

The growl/nip was a warning that he was feeling uncomfortable. You ignored that. Instead you smacked him and then tried to pet him again. That's like saying, "I don't care what you're feeling right now. You're going to do things my way or get hit." If you turn this into a power struggle, the situation will only escalate. Diesel will feel the need to defend himself. Violence begets violence.

You mentioned that you can't afford training. But, training doesn't have to be an expensive proposition with a professional trainer. In my view, what most needs to happen here is that you and your girlfriend need to educate yourselves on positive training methods so that you can re-build the bond of trust between you and Diesel.

You can borrow books from your local library or record some of the programs that are on Animal Planet if you have cable. There's also a list of recommended tools and resources about half way down our Dog Behavior Training page. If you can't afford something you want, ask a relative to make it an early Christmas present. In the long view, for a dog you love and never want to lose, it's a small price.

Good luck. Feel free to post back and let us know how things are going with Diesel.

Dont give up

A little extra help.
by: Anonymous

My pitty did that as she was getting older, it was usually jealousy that drove her to miss behave and then she didn't want affection later. I found that once I stopped using a tap on the nose as punishment she was much better. I taught her that when she was bad she had to sit in her kennel for a few minutes, never too long. I never closed the door to the kennel just had her lay in time out. I know I had a lot of time to train her, but I didn't invest anything but time and persistence into her training. If you look up Peace, Love and Pitbulls, they have tons of videos online that helped me get my dogs to be wonderful pets I wouldn't trade for the world!

Is he neutered?
by: Anonymous

This kind of situation makes me nervous. It sounds like the owners are not knowledgeable about dog behavior and training and it's difficult to evaluate what is really going on in this situation from a few short paragraphs. I agree with seeing a vet first. Aside from just not feeling good, there are conditions (such as those affecting the Thyroid) which cause behavioral and personality changes. Also, if he is not neutered, that could be a factor playing into this, although usually by the time aggression appears, it's too late to "fix" the behavior by neutering.

I would strongly recommend AT LEAST having him evaluated by a professional (who is pit friendly and has experience working with aggressive dogs/powerful breeds - i.e. probably not your local PetSmart trainer.) The trainer can observe him in his own environment and even if the growling isn't observed, there's a lot that can be learned about his personality that will lead to clues as to what type of aggression this is.

Also Check around because many cities now have free training classes specifically for pit bulls. My city offers free CGC classes sponsored by the Bully rescue in the area. Even if something like this is not available, do check with a bully rescue (most states have them) to see what local resources are available and if they can suggest a trainer.

I do think the owner could benefit from educating himself on dog behavior and training and it certainly sounds like he needs to change his own behavior towards Diesel, but I do not think he should attempt to "train" him out of his aggression without professional assistance.

Until this issue is fully resolved, I would not allow Diesel any contact with other people or dogs (that even includes your girlfriend if she is fearful of him, as she will only cause him to feel more uneasy). If guests come over, it is only fair to them to put him away. Be diligent in keeping him in the backyard or on a leash and if anyone approaches, tell them that he is in training and cannot be petted. Please do not create another negative Pit Bull headline.

Note to Diesel's owner. If he becomes too much to handle and is taken to the pound, please be up front about him having bit you. He will be put to sleep because of this, but it is not fair to pass him off to another well meaning person and have them or someone they know harmed. My grandma was attacked by a new foster dog I had before we were aware of his aggression issues (he was an owner surrender), so just be aware that he will eventually bite someone else if you pass him off and it could be a child or someone unable to defend themselves and no one deserves that.

get it together and do what it takes
by: Anonymous

1.) Is the dog fixed? If not, why?
2.) He states that training is cost prohibitive. Vets are expensive too. Regardless, for the well being of the dog and the safety of themselves, this dog needs to be evaluated by a vet and a trainer. As a pet owner its your responsibility to adequately care for your animal. Not to mention the HUGE liability on the owner's part if/when the dog bites somebody and what it does to the breeds reputation. Its better to shell out the cash for vet/training than a lawyer and medical bills. don't make excuses for why you can't take action to help. Its your responsibility.

All good advice
by: Anonymous

I'd also like to point out that, if he is cleared by the vet medically, the next step is to consult a behaviorist that works with bully breeds. I'm not talking about a trainer, though. You want someone who understands dog behavior and can evaluate Diesel. Hopefully he was just scared and your not respecting his discomfort is what caused this to happen. If that's the case I hope you can work with him to get past this phase.

Do be prepared to do the responsible thing if needed though. Don't rehome him if you can't handle him. Our breed of choice has enough problems against them now and doesn't need another instance in the news of someone getting attacked. If he truly is unstable please have him PTS. An unstable dog is NOT a happy dog and nothing you can do will change that fact. Pit bulls are exceedingly human friendly. Any human aggression should NOT be tolerated at all.

thanks i GUESS

Vet him NOW
by: Anonymous

When my dog was young..about 2 or so, she was subjected to a difficult transition with the family of moving and getting a new job. I had two kids 9 and 14.
She was definitely stressed with all the new changes, but we gave her extra leash time and taught her difficult tricks to keep her distracted..like balancing soda cans on her nose and "bang" which is pointing your finger at her and saying the word..she lays down, looks at you and drops her head..ha ha. I know sounds silly, but it forced her to have a little fun, even when she wanted to eat the fence.
One thing she did on her own at the new place was 'fetch rocks'..little did we know is that in spite of her being a powerful breed who could easily carry bricks and heavy rocks around in her mouth, teeth are just teeth. She had cracked one..and as the discomfort grew, she started avoiding our hands around her head. Can't have that around kids..they don't think at those ages.
We didn't hit her, so it wasn't like hand shy avoidance..the kids' dad, brilliant dog lover that he is had a suspicion she was in pain and took her in...and they discovered the tooth.
They pulled it and voila, she was back to her gentle self..she tells us when she's in pain or discomfort..we just have to listen.

My experience with holding them around the neck!
by: Anonymous

I raised two Rottweilers from pups along with my boyfriend. Gypsy, the female loved Greg my boyfriend. One thing she did not like was holding her head or cuddling around her neck and head. I told him that and he stopped doing it. She would growl, never nipped, but growled and I knew it wasa sign of being held down by my boyfriend or worse and she took it as an aggressive move.

Once he stopped holding her head or putting his face up next to hers, she never growled about anything again. It was evident that hold around her neck and face to her was someone trying to either hurt or control her and she didn't want any part of it.

Gypsy lived to 11.5 years and Rocky the mail lived 10.5 years in our home and they never bit anyone.

I think you slapped your dog's nose as a reflex, but I didn't see you being physically abuse although I told my boyfriend from day one to never lay a hand or anything else on these dogs or my rescue Pits because they see the hand as a weapon and will definitely rebel.

Others here have given some good advice, just wanted to add the part about some dogs not wanting to be held around the neck or close to their face.

Good luck, many others with more experience than I have given you a direction to follow to see if you can solve this dilemma.

Hitting the dog?
by: Anonymous

Oh great, another idiot who shouldn't have a Pitbull. When is this going to end up a bad news story about how the Pitbull attacked its owner, once again making the breed look bad due to stupid owners who don't know a thing about dogs.

I hate when people don't take a dog growling seriously enough to give it some space. Then they cry when they end up getting bitten.

Is this going to end up in a news story about the Pitbull suddenly "snapping" and turning on its owner?

Good Points
by: Gabrielle Vachon

As already mentioned, it sounds likely that there is a medical problem at play here, and the growling is him voicing his discomfort with being touched.

Neutering can be a factor as well. Although more so for the dog aggression.

Just understand that there are two aspects to dog training, commands and behavior. Even the best trained dogs will break a command if they are fearful enough. Even the best trained dogs can be aggressive. Looking at different training options does NOT mean you don't know how to train a dog.

Until you get to the bottom of the issue and rectify it, keep a close eye on him. If he felt the need to bite you, he might have a lower tolerance to a stranger.

I know I'm just repeating what has been said, I just want to say that they're all good points, even if they came accross as rude.

Good advice
by: Kathy

Like you, I was desperate to find answers when I opted to foster a shelter pit bull with fear issues. She wasn't aggressive, but the shelter wanted to euthanize her because "she could become aggressive." I was determined to find out everything I could about the breed and this is how I landed on this wonderful site. Gale knows her stuff and I would urge you to ignore the negativity and focus on the positive information you've received here. I pray for Diesel that this is nothing more than a manageable, minor health issue and that he'll be back to his loveable self in no time.

Maybe I missed it, but did you say whether Diesel was neutered? I don't know enough to say whether this would be a contributing factor, but I do wonder why it is that so many pit bull owners refuse to neuter their dogs. This is more of a general question and not meant to be accusatory at all. Perhaps Gale can comment on this.

Good luck to you and your family!

Benefits of Neutering
by: Gale

There are lots of good reasons to neuter or spay your pet dog. Here's a pretty good list of the benefits of spaying and neutering.

Of course, the best reason is to prevent random litters that compound the overpopulation problem and lead to the unnecessary suffering and death of domestic dogs.

A dog Diesel's age should be neutered, in my opinion, for general purposes. Whether it would have any real influence on his disposition at this point, is impossible to say. Results vary from dog to dog. My impression of Diesel's case is that this is more about the dog/owner relationship than it is about hormones.

Neutering has the most impact on a dog's personality when it is done BEFORE a dog reaches puberty. For a dog that's already an adult, it's simply the responsible thing to do.

This could help but idk
by: Anonymous

I have a pit bull too. She is the sweetest dog ever. If you hit your dog he/she will become aggressive. The only reason dogs attack owners is if you hit them no matter what. It's good to just give him/her lots of attention too. I am not sure what's wrong or if he/she feels threatened maybe. Hope this helps a little sorry if it doesn't.

I don't care what anybody says. If a dog can't be controlled by its owner, then it's time to put the dog down. People are more important than any dog. I don't mean to sound insensitive, but people and especially children can get seriously hurt or killed. Dogs aren't human and shouldn't be approached or treated as such. I wouldn't take any chances

I see this is a very old thread. NEW
by: Anonymous

I wanted to say something. People who responded to this post, made some very offensive judgements of the poster. I googled sweet dog becomes rude and landed here. I'm trying to help my small mutt through this stage. I'm very worried someone (old roommate) was cruel to him when I was not around.I also have a pit bull. They sure are people friendly. Just like people they aren't all the same. This woman was trying to do right by her dog. At least that is how I read the first part. I would have been extremely offended if I were her it sounded like the response was judgingthe poster with no reason.
Pit bulls are sooooo loving and kind normally, BUT when one isn't that doesn't mean it's all own the owner.

Sweet to serious biting NEW
by: Anonymous

I adopted a one year old pit bull 3 months ago. Sweet boy, NO training. He seriously attacked me the first week when I tried to take something from him. I hired a pit bull behaviorist, not a simple trainer. Oliver, my Pitt, is such a sweet personality, however, he bit me when trying to play with a ball and tonight, when my 9 yr old Lab walked by while petting Oliver, he attacked me!!! Serious bites on the chest and forearm. He was on a lease so I could get him under control.
I am so distraught because I made a commitment to him but what do I do?
Any thoughts/advise please!!!!!

Same thing happened to me only my adopted dog bit me down to the bone broke two bones in my hand that required emergency surgery and attacked my husband as well. Pls take the dog back to the shelter and be honest with them about why. I wish I would have. We even hired a private trainer who works wt pitbulls coming the next day. I will forever be scarred and have nerve damage in my dominate hand. I know its hard BUT having ur dog kill someone is even harder to deal with. I wish u the best!

Ear infection NEW
by: Anonymous

Our normally friendly mutt began growling when people would reach to pet him and we could not understand what changed. We, by chance, switched vets and the new vet discovered that our dog had very severe ear infections. It hurt him when people petted him. It never crossed our minds that he had ear infections

Why did people attack the author of this post... NEW
by: Ktforscythe

The author was looking for help. He realized whatever he was doing was not working and reached out to peopleat for help. He spoke up and reached out about his pitbull and people berated him, called him stupid, called hime an idiot, called him cheap, irresponsible, abusive. The list went on and on. This website was built, I'm sure as a place for pitbull owners to share advice, support and love for their pitbulls... not make people feel worse than they already do. The owner admitted to hitting the dog on the nose. I read that as bopping him on the nose. He didn't say he kicked or punched the dog and people were attacking him like he straight up was beating his dog. I'm pretty sure 99% of dog owners have bopped their dog on the nose or "spanked" their dog on the butt even if it was only once. He clearly felt bad for even doing that. If your dog bit you and growled and it was a new behavior.. you would probably be a bit distraught. If you reached out to others for help on a forum where you thought it was a safe place., and they insulted you, berated you and made you feel worse than before.. why would you EVERYTHING want to reach out for help again? To the people who replied to this six years ago... shame on you! You have made many people including me think twice about ever reaching out for help on a forum ever again... because people like you have to jab at other people to boost yourself up.. even to people who are scared, frustrated, and HONEST. Why would this owner EVER seek help again when it came to needing help for his animal when no matter WHAT he said.. people would pick it apart and find SOME reason to jab at. I came to this board to seek help in knowing why and what to do when the family I babysit.. their pitbull is caged when they leave any time I go near it he growls at me... I'm too afraid now to post about it seeing how other people treat people on this site.. no one enjoys when people insult them or berate them yet so many people do it to others...
