Getting a New Dog, Advice pls Options

I love dogs and have owned several guard dogs. Until years ago, one of my girlfriend introduced me to a toy dog breed and now I owned an imperial shih tzu for 2 years I loved dearly called Mouchi.

A few months back, I bought a Yorkie (yorkshire terrier) named Tasya which are very much terrier at heart. She was very active and naughty. Mouchi hates her. Tasya likes to charge Mouchi's ass like a bull for the fun of it, and at one time she was so naughtly excited chasing Mouchi's ass around the house, she fell down from the second story and to my dismay Tasya died. Mouchi seemed relieved though (IMG:style_emoticons/default/rolleyes.gif) and don't have to protect her ass from Tasya anymore.

I wanted to get another toy dog, especially a miniature schnauzer, a westie (west higland terrier) a pug or at the very least another shih tzu. It seemed Mouchi is not very sociable to other dogs and I'd like to have a dog who at least doesn't frustate her as Tasya did. What breed do you suggest I should get which may have compatible temperament as Mouchi's playmate?

Awww I'm sorry about your dog hon. That's sad.

Westies are FANTASTIC little animals and can be very very laid back, almost like a mature retriever, like I have. I do think that you're gonna have to get a mature dog though rather than a puppy so they are out of that irritating 'naughty child' stage that so upsets your existing dog.
