My yellow lab pup is about 7 months old now. I had initially planned on waiting to neuter until 18 months, however, his other testicle has never descended. I can sometimes see it at the base when he lays on his back, but won't come completely down. I'm trying to weigh the risk of possible cancer vs. neutering and stopping testosterone too early. I haven't been able to find any reliable info on neutering timeframe with a cryptochord. My best guess is around a year???? Thought I'd throw the question out to those who have way more experience than me.
You're more than likely seeing his bulbus glandis when he's on his back, not a testicle I would guess you're perfectly fine waiting until at least a year to neuter (I know people who have done just that), but if it'd make you feel more comfortable, I'd recommend contacting a vet that specializes in reproduction and ask their opinion... they tend to be up on issues like this and aren't the ones pushing neuters at 6mo.
One of my friends had a monorchird (only one down vs cryptorchid w/ none descended) and just neutered him at ~2. All was fine.

i got rex at 2 1/2 and he was neutered then. they found the missing teste in his abdomen.
he's now 11.
Thanks for the info.... definitely feel better about waiting longer now. Nicole... you're right, I was seeing the bulbus glandis (had to google that one) Always wondered what actually caused the tie!
