What is Zeuterin?

Making the Zeuterin choice means no anesthesia, no surgery and no shaving. Zeuterin is a one-time injectable all-natural zinc solution approved by the U.S. Food and Drug Administration as safe, effective and permanent for chemical sterilization of male dogs. Zeutering does not require anesthesia or surgery—just an ordinary veterinary visit. When your dog gets Zeutered it means:

  • Permanent neutering in 99.6 percent of all dogs
  • Low risk of post-procedure complications: Swelling and poor appetite are common post-procedure reactions, and these will typically resolve on their own within a couple of days, with no need for follow-up veterinary care
  • Typically costs less than surgical neutering
  • Lower-cost licenses for altered pets, just as with surgical castration
  • While surgical neutering(Castration) eliminates nearly all testosterone, the study on Zeuterin treated dogs found testosterone levels were 41 to 52% lower on average as compared to intact dogs after 24 months, which may benefit the health of your dog

How Does Zeuterin Work?

Zeuterin is injected into the center of each testicle. The procedure does not require anesthesia, but dogs will need to be sedated to help keep them still. Most dogs are ready to go home shortly after. Normal swelling will occur and will usually resolve itself within a day or two. Most doogs do not need follow up care. Since Zeutered dogs retain their testicles, they are typically tattooed on their inner flank with a small green “Z” to identify them.

For the first few days after injection:

  • Restrict your dog’s exercise to leash walking
  • Do not allow your dog to run, jump, or engage in play activity
  • Do not allow your dog to lay on hard or wet surfaces
  • Do not allow your dog to lick or bite the scrotal area

Mild, temporary swelling of the testicles is an expected reaction to the injection, which you will notice within 24-48 hours after the injection. Your dog’s testicles may remain slightly enlarged but non-painful for a few months after the injection. To minimize the occurrence of adverse reactions, such as scrotal irritation, inflammation or infection, it is critical that you closely monitor your dog’s activity post-injection and that you take all precautions necessary to prevent injury to the testicles and to prevent your dog from licking or biting the scrotal area.

Make the Right Choice

Preventing unwanted litters is part of being a responsible, caring pet-owner. When you choose Zeuterin, you’re also thinking of you own dog’s comfort and health. Zeuterin is the only injectable sterilization procedure approved by the FDA for male dogs. And it’s a money-saver in most cases, as well.

Zeuterin is not intended for use in dogs with undescended testicles, a disease or malformation of the testicle, a history of allergic reaction to any of the components of the drug, or a pre-existing scrotal irritation, dermatitis, or transmissible venereal tumor.
