My 5-year-old chihuahua is not very pleased with my choice to get a miniature australian shepherd puppy. I've had the puppy for 6 or 7 weeks, and my chihuahua hasn't shown much interest, apart from growling at her when she gets too close or chasing her down when she nips at him (when she tries to herd him).
However, while my chihuahua looks like he might be getting used to the puppy, he's started to direct his anger completely toward me. I know he's upset with me for bringing a new dog into the house after he's been #1 for so long, but it's gotten to the point where he bites (or tries to bite) me every time I pick him up. He snarls at me when I get near, and he no longer wants to eat or go outside for the bathroom. Most days, he barely leaves his crate. I know this is a common problem, and I expected some sadness, but I'm incredibly bothered by his anger and hostility toward me, particularly because he's his old self around other people who he's familiar with.
What can I do to let him know I love him as much as ever but won't tolerate his aggression? I miss having a dog who didn't try to bite me every time I get near him!View Thread
