Anyone else's dog started marking and getting aggressive lately...?

So my 8-year-old Miniature Poodle, Sima, has recently started marking inside the house and getting super aggressive toward the other dogs. This only started about 4 months ago. He’s not neutered and our vet thinks it might be anxiety-related. I’m wondering if neutering him would help or if we just need to do a ton of training… Any thoughts? Anyone gone through this?

Yeah, my dog did the same thing at one point! Neutering didn’t really fix the problem, but it could help with aggression. I’d suggest focusing on training. Have you tried the ‘nothing in life is free’ method?

I don’t think neutering will fix the marking, especially since he’s older. You might wanna try belly bands while you’re training him. It helped a lot with my dog.

My dog was doing something similar but with more anxiety. It was way worse when he felt like he wasn’t getting attention. Training daily really helped, but be patient!

I’m wondering if it could be related to dominance too. Have you tried any training to show Sima you’re in charge?

I’m with you on the neutering hesitation. It probably won’t help with anxiety-based issues. The training is definitely the way to go.
