(Memphis) Move over scalpel, there’s a new way to fix male dogs.

“It’s a chemical castration. So instead of a typical neuter surgery which the dog has to undergo anesthesia it’s a pretty invasive surgery,” Stephanie Bennett with Mid-South Spay and Neuter Services said. “This is actually just an injection of a chemical into the testicles of the dogs.”

The compound called Zeuterin is so new, Mid-South Spay and Neuter Services is still waiting for its first shipment.

Zeuterin hit the market last week.

“We are hoping to increase our numbers and help more animals through this service,” Bennett said.

Bennet’s group spayed and neutered 31,000 pets since 2005. It hopes this shot increases the numbers since no anesthesia is required and it takes only seconds to administer.

“Now that Zeuterin is on the market that just gives our client another option.”

The drug company says it is 99 percent effective for the lifetime of the dog.

“It’s a non invasive surgery. It’s relatively painless. The dog will be sedated slightly. It’s mainly to keep it from not moving its a same days service,” she said.

But it’s not for every dog. Right now the FDA only approved the chemical for male dogs three to ten months old, which some shelters say won’t work for them since right now you can alter a male puppy at eight weeks.

Others worry you won’t be able to tell if the dog has been fixed, but Bennett says the dogs her group will inject will get a tattoo and says education will be key.

“I think as technology moves on and we have these new types of new tools to prevent pet overpopulation there will have to be a shift in how people view intact male dogs,” she said.

This new tool will save money, since it’s generally cheaper than the old-fashioned surgery.

“Full service vet it cost up to $300 to be fixed,” she said.

Spay and Neuter Service of Memphis will charge $75 to $125 for the shot. It’s the same it charges for its already discounted spay and neuter services.

Bennett hopes this service will convince more male dog owners to get their pets fixed.

“You get to keep your animal intact but you’re still helping to prevent pet overpopulation,” she said.
