I really think it's the smell from being at the vets.....they come back with so many scents and smells that the other's don't know what to make of it so they act out, then poor Decker only gets more stressed. What I do even after routine visits to the vets is to try to keep them separate from each other and then I try to spend time loving whoever just came back so that individual (or two in my case) get my scent back on them. Sometimes I put them in/on a blanket with their scent on it to try to get things back to normal.

Lori, I'm sorry this is happening, I know how stressful it can be. (((HUGS))) Meg
