How does a puppy need to be to get nurtured?

PAL Clinic spays cats and dogs at 12 weeks of age. Kittens start breeding at 16 weeks of age.

Any time after 8 weeks if age

"A male dog can be neutered any time after eight weeks  of age. A few years ago, most veterinarians advised waiting until puberty hit at about six months, and some still make that recommendation" - from a Google search. Hope this helps! Xo

I think 8 weeks old
