When to Spay or Neuter Your Pet. 1  For dogs: While the traditional age for neutering is six to nine months, puppies as young as eight weeks old can be neutered as long as theyâre healthy. 2  For cats: It is generally considered safe for kittens as young as eight weeks old to be spayed or neutered.
Best to spay before if at all possible - usually around 6-9 months old. If the dog comes in heat before you get spayed, you will need to wait about a month after she is finished and you will have to keep her on leash for potty - never let her outside alone and sometimes have to crate her inside (or clean up blood spots).
