My dogs liked my ex when I lived alone but once we moved in together the dogs became scared of him. I never saw any abuse but they definately did not like him and did not want to be anywhere near him, physically trembled in his presence. When I left him and moved to a new place all was well with the dogs - then I relapsed (I know, I know) and he stayed over - I should have prefaced this by saying my dogs have their own bed in my room and they always sleep with me every night without fail - so when he stayed over lily the codependent Jack Russel would not sleep in the same room with him. She slept downstairs alone... She's 9.... She's never slept alone before. My 3 dogs love everyone - except him. could there be any other reason than he hurt them?
