Planning to spay or neuter your pet? There are many options in addition to traditional surgical sterilization practices. The decision depends on your pet and your needs. Nonsurgical options include calcium chloride dihydrate and Zeuterin. For situations when hormones are important to preserve (such as in large-breed dogs), ovary-sparing spay and vasectomy are offered by many veterinarians. In order to assist pet owners in finding a veterinarian willing to perform an alternative procedure, we maintain a listing of veterinarians on our website. Check out our recently updated Veterinarian List as well as more information on alternatives under the Dogs & Cats tab.
