I know you will all think I am mad, but our long haired chihuahua (1 year old, had him 3 months) "pretends" to be afraid of me when anyone else is around. When my partner is out he is all over me like a best pal. But as soon as she gets home he exhibits all the signs of fear towards me. If he was human I would say it is an act to paint me in a bad light. I have even considered borrowing a bodycam to video his behaviour when my partner is out because I am not convinced she believes me. Why is he doing this?
