Advice Needed Random aggression increasing in 3 yo dog
Hello! I have a 3 year old dog who I adopted about a year ago. He’s a lab staffy mix and super sweet. I delt with a lot of separation anxiety at first with him, but was able to crate train him and start him on Prozac to help. He does great now and doesn’t even need to be in the crate when I leave him home alone. I work night shift and go out of town sometimes and am lucky enough that my apartment has its own dog daycare where he goes a few times a week, it’s only roughly 5-7 dogs, many days less than that and the girl who runs it is absolutely wonderful. I would say over the past 3-4 months he’s been having increasing instances of random aggression towards other dogs with no common denominator (no food, toys, dog wasn’t bugging him etc) He’s not leash reactive at all, most of the times he straight up ignores other dogs when he’s leashed. But he’s now had 3 strikes at the daycare and other instances I’ve been there for where he randomly goes for another dog. He had some resource guarding in the past when my roommate got a dog but that only happened when the other dog went near his food bag/bin or main source of his food. He does completely fine with treats/snacks etc. He had no issues with any type of dog prior to these past few months. I have a vet appointment booked to rule out any pain or medical causes and am going to start training next week. Has anyone had this occur with an already mature dog? If so do you guys have any tips for me or sources on helping train with him? I won’t be having him go back to daycare or any sort of park anymore until I am able to really nail the source of it or just help his training improve. I’m just so sad and fear I may have caused it somehow but I can’t think of how and I am so scared of him hurting another dog. Thank you
