The Last picture is of his dad full grown 

I have 1 boy t cup yorkie he's almost 4 mo old his father was only 2 lb full grown and the mother was 4lb. I do not have akc papers because I just didn't want to spend the money to do so I'm not the type to even go to a dog show or any of that crazy stuff. My dogs are my body gards at least they think they are lol but if you want papers they have a dog dna test that will give you all the info you need to register him if you want to do so it cost around 60 bucks but that's on you if you chose. My baby boy is about 1 lb many a little smaller he is potty trained if you actually take him out but I still would keep a look out for sniffing. Also he does good in a kinnel if he has a dog bed and another thing he's use to other dogs and has always Ben with his mother so you might want to have other small dogs please text 785 259 9044
