I am considering buying a dog half pekingnese and half Chihuahua. It lives in a shed with other dogs and occasionally comes in the house. Should I buy this dog?

Hi!

I'm hoping you can answer my question. I am considering buying a dog half pekingnese and half Chihuahua. She is 1 year old. This dog lives outdoors in a shed with other dogs. She comes in the house when grandchildren come over and they play with her, but when she jumps out of your lap she wants to go outside. Of course she is not housebroken. I personally don't think this type of dog should ever be living outdoors. The owner breeds dogs and decided to keep this one because it is so unusual, but she said she would consider selling her. Do you think I can still train this dog? She is basically an outdoor dog but we want her in the house with us. The seller is very honest, she said she is a sweet dog but still very active. We went to look at puppies she had, but this dog caught my eye, so I really didn't get to hold her or interact with her. What do you think? Wouldn't I be taking the same chance if I brought a puppy home?

Thank you so much.
