Received my 9 week old male chi pup from breeder and vet was not able to feel his testicles. They have not dropped yet. She will continue to monitor. I purchased him with breeding rights and desire to eventually breed for the love of improving the breed only and in no rush. Would not breed until he is about two years old. In any event, the breeder is willing to sell him as pet but adore him already. Should l be worried they will not drop?
