Hey everyone! So I need a little help in figuring something out about this puppy that I'm thinking about getting. I have always had dogs my whole life, and lost my little baby (she wasn't a Yorkie she was a mixed breed of a spaniel and a border collie...) She was 11 and had heart problems from birth and one day her heart just stopped... It was very hard loosing her but I am ready now for another dog in my life and since I always wanted a yorkie I decided to look in to this. I found this woman who has a 2 kg blue yorkie and she had two puppies, which one of them I'm thinking about getting... The thing is, she only has the mom, she says the dad is 1.80 kg and the puppies are going to be small, since I don't really know much I wanted to show you the little one and see what you guys think, does he look pure breed? From your experience with your own dogs, does this 1.5 month old puppy look like he's really going to be small? Is there anything else I should know/ask her? I've only seen pictures, I'm probably going to her house tomorrow to see him... Thanks ahead for the answers
