Good that he hasn't been yet . Perry was neutered at around 6 months (he is a rescue and they tend to neuter/ spay earlier than you might want/ recommend) before I got him (I got him at 8 months), but I don't think he's taller than "normal" because of it ...No he has not! The vet said not until fully grown which he said was 9 months!
Yes we have papers that he’s purebred but it doesn’t matter to us. Just hope he doesn’t end up the size of a sheep dog lolThose are unusually long legs for a full Havanese. Did you get papers? If it matters to you you could do a dog dna test. If you paid for pure Havanese and you ended up with a mix, you shouldn’t pay the same price as a full Havanese.
Otherwise, he’s a handsome pup!
