Spaying a puppy improves the dog's prospects for living a longer and healthier life, and it ensures that she does not go into heat, according to the American Society for the Prevention of Cruelty to Animals. Spaying a puppy saves her owner money in the long run, and it prevents the pup from bearing offspring that contribute to the homeless pet population, states the Humane Society of the United States.
Spaying a puppy before her first heat reduces her chances of developing uterine infections and breast tumors, advises the ASPCA. This means that her owner avoids the expense of treating these potential medical issues, notes the Humane Society of the United States. The owner also enjoys the company of the dog for a longer time, as studies indicate that spayed female dogs have lifespans that are 23 percent longer than those of female dogs who remain intact.
Spaying a dog saves the owner from dealing with the vocalizing and frequent urination common in unspayed female dogs when they go into heat for several days every three weeks during breeding season, states the ASPCA. It also means that the dog cannot have puppies, saving the owner the expense and care necessary in raising litters of puppies and keeping the dog from possibly adding more puppies to the homeless pet population.
