neutering my male Rottweiler pup
what is the best age to neuter my male rottie?
Neutering a male dog not only prevents them from fathering puppies, it also provides protection against reproductive order tumors, cancers and other conditions.
To get the maximum benefits of this protection, you should have your pup neutered between 4 and 6 months of age.
There is no age at which it MUST be done, and can be done earlier (if your vet agrees), or later (even much later) - but the best health benefits are obtained by neutering before 6 months.
Hope this helps. Best of luck with your pup.
