Dr. Schulz did a special chemical sterilization on 4 dogs with a product called Zeuterin. The drug is injected into the testicles and causes them to shrink up 50% and renders the dog infertile within a month. It requires a very mild sedation and accurate measurement of the testicles to dose them appropriately. The procedure is labeled for dogs 3-10 months old currently. After doing training in California in February, she is now certified to do the procedure. Thanks to Ark Sciences Charities for supplying a grant to help with the neutering procedure! There is more neutering in our future at Red Lake.
