Be sure to ask your breeder about possible delays that run in his genetics. I have a yorkie that had a sire that didn't descend until he was almost a year old and had I not known that when I took him in for his vet visit around 6 months of age, I would have wound up getting him neutered by the advice of the vet. The vet could not feel anything at all...I couldn't either. On occasion it was possible to feel them up in the abdomen, but not very often. The vet told me that it was very unlikely that he would descend. I decided that I would give it until he was a year old before I would neuter him based on his genetic delay. Glad I did....he's 11 months old and now fully descended.
