My husband and I have had our chihuahua for about 4 or 5 months now. When we first got her she was a bit scared and nervous and would occasionally snap at us. But then got use to us and has not done that since. I am now 6 months pregnant and for the past month of my pregnancy I can not go anywhere near her. She will snap at me if I even get close to her and constantly growls at me. I cant pick her up and or even pet her. But then other days its back to usual where she is so loving to me. She loves me one day and hates me the next. I am worried about when I have our baby if she is acting like this I don't want her near our child, I cant risk her hurting him. Yet I don't think I could part with her.. I don't know what to do??? And I cant afford obedience classes as someone on another site suggested, not in our budget AT ALL. I was just wondering is this something that chihuahuas are known to do??
