About 2 months ago i purchased a "Yorkie", We wanted a girl to serve as companion to my Yorkie boy YOYO. She got home, she was so tiny! and totally could have fooled anyone. However now that she is almost 4 months old... Her hair is growing slow, she is gaining too much weight and is getting really big... she does not look like a Yorkie anymore. I feel betrayed by this individual. She is lovely me and my partner love her and spoil her as much as my YoYo. I need help thou, I am having difficulties potty training her...When YoYo was a pup he learned very quickly but she is messy, and her attitude is different from Yorkies, I am having a hard time understanding her.. Seems like she chose my partner as her master also. Please help me understand this behavior if someone knows about shorkies, snorkies,
