He is a handsome boy! I do not like how he advertised as tea cup though. He is an adult Yorkie, who has beautiful markings. MAke sure you get a health certificate. I would ask them why they are rehoming him?
Are you training your dogs as therapy animals for other people? Hospital visits? or for your needs or family?
I have a Yorkie pup. who is my service animal. I am curious as to what you are doing in regards to training?
