I have a 3 month old ruby cavalier who is scheduled to be neutered at 4 months old; he does have one undescended testicle as well. Is that too young? I am sure the undescended testicle is a factor to the early neuter. For those that neutered their pups early what was your experience like? I have read that some pups grow a little taller and/or coat texture changes. He is a beautiful pup and would like him to mature to what nature intended but the undescended testicle is a concern. Thank you in advance
