Bob's just about better now, but Butters is suddenly behaving aggressively towards him!! This isn't due to the vet smell, Bob's been home from the vet for days now. It just started arbitrarily last night. What I suspect is Butters is feeling left out because first Spirit was very ill and center of attention, the Bob was even worse and we've been all over him. I thought I was paying attention to Butters but maybe not enough? So after 2 unprovoked attacks (which we handled very calmly and I talked Butters "down" and assured him he wasn't in trouble) I gave him lots of extra special attention. Any thoughts/help? Has anyone used one of the "calming" collars-they seemed to be more for destructive or anxious behavior but I'll try it, they're cheap enough if it will help.
