We have an 8 month old puppy, male, named Conway. His testicles have ways just been a furry little mound underneath his penis. Yesterday he was full of energy as always and seemingly fine. This morning, he was pretty lethargic, which isn’t entirely unusual as sometimes he’s just that way in the morning, but typically back to full energy by the afternoon. We noticed about 2 hours after being up and about, he was sitting down And laying very slowly and then happened to notice that his testicles are huge and instead of being the small mound of fur it had been, look like grown man, fully developed testicles. He has recently started lifting his leg to urinate. The fur around his testicles looks as though he’s been licking them, though we haven’t seen that activity today, so we’re thinking he did that over night. He’s not whining and doesn’t appear to be in pain aside from the fact that he is taking his time while sitting or laying and he’s been very lazy all day. He does appear to have two fully descended testicles and has let us touch and inspect them with no issue. Is this normal? Anyone else experienced anything like this?
