Due to a death in the family, I've been dog-sitting my SIL's dog a lot lately. Bella is a pomeranian/terrier/chihuahua. she's only about 5 1/2 months old. She just started puppy classes. She's a really sweet, adorably cute dog, and she has really bonded with me. But I don't think she was propperly socialized because she really doesn't like people. She barks at everyone, my husband included. It took her a while to get used to me, and now she's like a velcro dog. But when my husband comes home, she flips out and growls and barks. He talks soflty and gets down on his knees and she comes to him to be petted and she's fine. But any little thing, like standing up too suddenly, or putting his arm around me will make her start barking and lunging at him. Also, she hates it when people kiss around her. She'll freak out if my husband and I kiss, or even get too close to each other, and my SIL said Bella does the same thing around her. Any suggestions on how to improve this situation???
