To Zeuter or Not to Zeuter


That is the question. Zeuterin is an injectable method of neutering male dogs using a combination of all natural compounds including zinc gluconate, arginine, and water. Zeuterin is the only FDA-approved method of sterilizing dogs without the need for surgery. Unlike surgical neutering, with Zeuterin, the testicles remain, and dogs maintain about 50 percent of their testosterone production. General anesthesia is not required, but sedation is used. Many pet owners have questions about the procedure – a few of which we hope to address here.

What are the benefits?
Because it is a non-surgical method, no anesthesia is required, rendering the process quick and relatively painless. Zeutering also results in fewer post-castration complications. Also, the compounds used in Zeuterin are safe and non-toxic. Your dog will have no physical alterations after the process, and zeutered dogs can experience a few of the benefits of testosterone, such as improved muscle tone and reduced risk of obesity.

Is it effective?
In a field study, 99.6 percent of the dogs that received the injection were sterilized.

How can you tell my dog has been sterilized?
Zeuter patients get a small Z to signify that they have been sterilized as it is hard to tell since they still have their testicles. You should also keep your dog’s microchip records up to date.

What are the risks?
Unlike surgical castration, zeutering doesn’t remove the testicles, which means testosterone, the hormone associated with some prostatic diseases and cancers, is still present. The presence of testosterone also means your dog may still exhibit behaviors such as aggression, roaming and mounting that are often eliminated with surgical castration.
