Unhappy Dogs showing aggression to other dogs over time

Hi everyone, I'm new here. I adopted my first dog, Scout, about 3.5 years ago. He's now about 5 years old. I adopted a second dog, Bailey, about a year ago. She's about 1.5 years old. Scout is a chow beagle american staff type of mix. Bailey looks like a black and tan coonhound mixed with beagle. Not sure exactly their breeds.

Scout was very anxious around men, including myself, when I first adopted him. He didn't like being around men without dogs or women being around. I figure he may have had an incident or been mistreated by men. But after a few weeks he started warming up. Around people, he's generally great (unless it's a guy he doesn't know and he will bark and bark and bark). He also became super friendly with other dogs and would chase and run and have a great time, very minimal barking if anything. About 1.5 years ago, I noticed he started to get pretty barky with other dogs, mainly male dogs and puppies. Even bigger dogs. If I took him to the dog bar, and a dog sniffed his butt or had it's face near his face, he would turn and lunge at it and bark. It wasn't really a "fighting" bark or aggression, more of a "Hey get out of my face!" His tail would be up and wagging, and then he'd walk away." Now this is almost his entire interaction with other dogs. He rarely rarely ever chases or plays. Just barks at them. This really concerns me, and I have no idea why this started happening.

Today, I took both my pups to the dog bar, and Scout did his usual barking at other dogs. Bailey, however, who is normally the sweetest and most playful girl, got really aggressive with a puppy, jumping on it and was aggressively growling and snapping at it. I had NEVER seen her do this. It didn't seem to be prompted by anything. A minute later, same dog, she did it again and I had to take both pups out of that area. I took them to a different spot with only a few other dogs. Scout still his same old barking. But Bailey started chasing and playing with other dogs. So I thought maybe it was just that one dog. But then there was a dog she started chasing, and when she caught up to it, it went down on its side and she jumped on it and once again aggressively snapped at it and growled. The other dog whined and I had to break it up. A minute later, another new dog shows up, and unprompted, Bailey walks over, looks at it for a minute, and is totally fine. Then she just starts growling at it for no reason! I finally took the dogs home.

I'm lucky nothing has happened. But I'm REALLY concerned now that something is wrong with both dogs. I don't know if Bailey is picking this up from Scout, and I don't know why Scout would have started this. I really need some input about how I can deal with this situation and help them both be fine again. I feel terrible for Scout, not really playing with dogs anymore because of the barking. It's really off putting to other dogs and their owners.

Bailey's aggression is scaring me as she has been completely fine before this. I'm concerned she will end up drawing blood in another altercation. I would really appreciate any advice

If there's food around it could be resource guarding. If I had a dog & I was worried she might bite, I would muzzle her. I wouldnt want to but I would feel I need to do the responsible thing, at least until the behaviours sorted out. Sometimes they change as an adult dog matures from puppy hood. I would work on training so the dogs have better manners & respect & not take them places with other dogs & food until better behaved. is offline   Reply With Quote
