When to Spay. If your lab puppy is at least 6 months old, the time is right for spaying. Some vets, humane societies and breeders recommend spaying as early as 2 to 4 months, but the traditional age is 6 months. A lab puppyâs first heat typically occurs between 7 and 12 months so you likely want to spay before then.
Research over the last 15 years with animal shelters has shown that younger animals actually recover faster from modern anesthesia. She absolutely should be spayed before her first heat. First heat typically occurs between 6-9 months of age, though a few dogs can have a heat as early as 5 months. So as early as your vet will do it is best. There is absolutely no benefit to your dog having a heat cycle; in fact, risk of reproductive cancer increases with every heat cycle a dog has.
