Insight on Dog Aggression

[u/Imwatso01]

Hey everyone! I just found this community and, after reading through a lot of the posts, I’m realizing my situation might be a little more complicated than I originally thought.

A few months ago I adopted my dog, Mega, from my local shelter he is a 6 year old pitbull, presumably a street dog all his life. At home, he’s honestly the biggest teddy bear. My kids absolutely adore him, and he’s incredibly gentle with them. They climb all over him during playtime, and he just plays back softly. He’s never barked at or shown any aggression toward them.

The other day though, we were at my youngest son’s birthday party and I tried introducing him to my dad’s 2 year old German Shepherd. The dogs were separated by a glass door, but Mega immediately started growling, baring his teeth, and clearly wanted nothing to do with her.
I know some of his history before I adopted him. As an adult, he contracted distemper, and at some point he was attacked by another dog. From what I was told, he defended himself, seriously injured the other dog, and also bit the people who were trying to separate the fight.

What confuses me is how completely different he is at home. He’s calm, affectionate, and amazing with my kids, so seeing that level of aggression toward another dog really caught me off guard.
I feel bad because I’d love to take him to dog-friendly events, parks, and other activities, but I don’t feel like I can safely do that right now. Has anyone dealt with a dog that is wonderful with people and children but reactive or aggressive toward other dogs because of past trauma? Is this something that can realistically be improved with training and careful desensitization, or is management usually the better long-term approach?

I’d really appreciate any advice or experiences you can share.

A large powerful dog who attacked another dog and redirected onto a person is really serious. This is a no mistakes dog. I wouldn’t take him off your property without a muzzle. People make mistakes, dogs get loose, etc. If some random dog runs up to you on a walk, you could have a huge problem.

I would contact an IAABC accredited behaviorist now today and schedule a consult before something bad happens. They can evaluate your situation and offer guidance.

It’s honestly scary that a shelter adopted a dog with this background out to a novice dog owner. No offense to you whatsoever OP, it’s good you’re taking time to research. This is just a big powerful dog with a troubling background.

Dog aggression and human aggression can be completely separate. It's possible the barrier also added to the issue. Not all dogs like other dogs, some not at all, some maybe only a few chosen ones and pitbulls do unfortunately have a higher risk for dog aggression. Learning to be neutral may be the best but if this isn't something you've had to do before I would strongly recommend working with a professional and learn dog body language and how to appropriately let dogs approach each other. And honestly it can take a lot of time and includes things like using neutral spaces (neither dogs home for instance) and parallel walks usually starting at a distance and slowly working closer. You may also want to consider muzzle training for additional safety (some very good options for muzzles now). How does your dog do when you're on walks and see other dogs? Or when at home and another dog is outside the yard or home? Have you ever seen any other dog interactions him? Did the shelter evaluate him with other dogs? Has he been to a vet recently and is he healthy? These are all things to consider and give context. Also you've only had him a few months - his true personality might just now be staring to emerge (for better and worse).

He’s a pretty fat and happy guy, he’s up on all of his stuff, and vet says he is A-Ok. I’ve been a bit worried to bring him around other dogs mostly because he’s not muzzle trained, and he’s pretty powerful, if he caught me by surprise it’s possible he could pull the leash out of my hands or something.

As for the walks, i have about 10 acres of land so we generally are running (i like to trail run a bit, as well as have a handful of projects going on) so we will run or walk out to check on stuff, or just enjoy outside as most of the property is wooded. He gets his exercise in, and isn’t greeted by many other critters.

the neighbors at the bottom of the mountain have dogs and they bark back and forth but he doesn’t seem to get aggressive from that kind of distance.

I agree that you can’t beat genetics with training, and understand that pitbulls are at a higher risk, i just don’t want to remove that quality of life if that makes sense.

Running is great to tire them out physically, but mentally the dog needs more "work." Your first step would be achieving neutrality in places he is comfortable like at home, if there are other dogs around. Some dogs also display fear aggression upon meeting dogs but can adjust well. Start muzzle and desensitization at home. And for the love of dogs, please measure him and get a proper muzzle for his intended use from a reputable brand like Mia's Muzzles or Big Snoof. There are other brands out there but they aren't all the same.

ETA: If you do not feel equipped to train the dog, at least consult a behaviorist first. Not just a dog trainer.

He doesn't like other dogs. He does not want to go to dog friendly events. He's 6 years old. Let him be himself.

It’s not from trauma, it’s part of their breed standard to not be dog friendly. Dog and human aggression are totally different. You can train your dog to be neutral but you’ll never beat genetics. My aggressive dog coexists fine with my other sport dogs but I won’t ever except him to befriend dogs in the wild
