Okay my boyfriend has a Chihuahua she's a girl and has always been an inside dog.. She used to not let me get close to my bf but then she got used to me and started sleeping with us in the bed. I have a 5 year old son he loves animals . he always wants to play with her and pet her and she bites him making him bleed. I noticed ever since i got pregnant she bites me or doesn't want to be near me. Since we live in a small studio my room is small and my oldest sleeps with us and so does the dog. She has always slept with my bf in between his legs but ever since we moved in i gave her a warm blanket and space in the corner of my sons legs . since his little he doesnt fully reach all the way to the end of the bed. So she always comes to sleep in between me and my hubby and when i move her she bites me or growls. Until my bf tells her to move she leaves. I am 31 weeks pregnant so i twist and turn because of my tummy . i feel like she hates me and my son. I am scare that when baby gets here she might bite him too.. What does this mean? She has never been like this..
