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 Answer: The best age is between 4-6 months, so you spay BEFORE your dog ever goes into heat (but after your pet has had all necessary vaccines). Spaying before the first heat cycle decreases the chance of later developing mammary tumors (breast cancer) by 97%.After the first heat the chance is decreased to around 80-85%, and after the 4th heat there is almost no decrease.deally she should be spayed between 4-6 months, BEFORE her first heat cycle. This will help reduce the chance of breast cancer later in life. Also the spay surgery once they have had one heat will be more involved.
