He's very cute...but did you listen to anything we said in the other thread?
I really think it will be hard enough with 2 puppies!! When Carl was a puppy he was pretty good until like 3-4 mos when he turned into a little terror
I would focus on the two beautiful chis you have, and give them all the attention they deserve, before you get another one.
For not being a BYB your breeder sure has a lot of chi puppies...all the time.
