The cost of spaying or neutering your pet depends on many factors. For example, a large dog will cost more than a small dog; if your pet is overweight or in season this can also add to the cost. Contact your veterinarian to get a more accurate idea of the costs involved for your pet.
The cost of spaying/neutering is really quite small when compared, for example, to what you will spend on food for your pet over its lifetime. Also consider the possible costs if you do not spay and neuter. If your pet should wander off in search of a mate, you may be faced with paying fines and impoundment costs. You may also be faced with the additional costs of maintaining puppies or kittens for whom finding homes may be difficult. Worse yet, think of the costs should your pet be injured while roaming for a mate.
