Was out for a walk with my 4 year old border terrier and we met up with another woman who I know through walking my dog and her BT. We have walked with them a few times but the last time which was a few months ago her dog started a fight with another Bt and my dog jumped in amongst it her dog got bitten on the ear although we didn't see who did it.
Anyway today it happened again her dog became aggressive with another very young BT and my dog jumped in again barking really loudly and going for her BT's ears. So it was probably him the last time too. I never had any issues with aggression before, he can be a bit barkey and excitable if he meets another daft dog but has never been aggressive before. I think we will have to avoid going out with the other BT now but should I be worried now that he has done this? I'm usually careful about approaching other dogs anyway but wondered if there is anything else I can be doing?
