OK so I have one male dog, first one. Can't say I remember when the balls dropped but I believe it was rather late. Not there for months, then WTH are Those

. That said, if a vet was to be concern about possible cancer and need to neuter. Whelp that won't happen for years, even if one of the boys is retained.My reading on they subject is that crypto- is believed to be a x-chromosome condition which is why it's so hard to breed out. Girls not having balls and all that. I hear sometimes vets can move one of the boys out before the capsule closes, but you would need advise from more of a vet type that isn't neuter at birth. Feeling is it be better to get an opinion from someone-vet that knows more about reproduction biology that just cutting it out

. Wouldn't consider removing a field dogs hormones until they are fully developed >1.5 yrs +, to get muscles structure and bone stability; after that I might worry about such things. Cancer won't be a concern until at least 5+; a problem for another day. Even then I know people that have just remove the retain testicle, as they wanted to maintain hormones. At 5 mts. a Pup has a lot of growing to do; hormone related. So why not wait and see if balls drop or not, at least the dog will be able to develop correctly.
