These pet owners just don’t give a shot.

Skeptical Brooklynites are joining the anti-vaccination movement — balking at immunizations for their pooches or pussycats — in fear that the shots may cause autism and other health problems.

“People are reluctant to vaccinate. They don’t want to put anything in their dog,” Dr. Stephanie Liff, the Medical Director at Pure Paws Veterinary Care in Clinton Hill, told The Post.

She says that on average, at least one owner a day will push back against vaccines, and some have even turned them down because they’re worried their pets will become autistic.

“[One person] had a child that was autistic, and she had an immune disease, and she didn’t want to vaccinate the dog,” Liff said, adding that the owner was “very holistic.”

“We were on different sides of the argument. I made the recommendation, but she didn’t take it.”

While there is no evidence of a link between autism and vaccines — in humans or dogs — many New York parents and owners are correlating the two.

“The mercury in the vaccines is extremely dangerous,” claimed Toti Little, of Prospect Park. “Vaccines are not safe, and regarding animals, we did have a dog — my husband and I — and chose not to vaccinate him.”

Anthony Kaidan, 27, of Bushwick, told The Post he used to be a believer in vaccines but became worried about his two dogs, Cookie and Rue, after one of them had a bad reaction a few years back.

“Why should we continue to blindly vaccinate dogs when you could spare them with an easy test?” Kaidan said, in reference to titer tests, blood tests that check for immunity and antibody levels.

Randy Klein, owner of the Whiskers Holistic Pet Care shops in Queens and Manhattan, says it’s always been her opinion that depending on where pet owners live, the incidents of having a negative reaction to the vaccine is far more common than having a problem from the disease they’re trying to prevent.

“We started these [shops] 30 years ago as a direct result of a dog of ours developing bone cancer,” she said, describing her collie-husky mix, Tiffany-Ann.

“We vaccinated her every single year for her short 13 years of life,” Klein said. “Ever since then, I’ve been made aware of the potential risks of doing it — and as a result, our subsequent personal pet lived to be 16 and our dog after that lived to be 18. We also had three cats, which lived to be 26, 27, and 28. They’ve never been vaccinated.”

Despite the paranoia, Dr. Liff insists that there’s no research supporting the claim that inoculations can cause autism or other health problems.

“Even on the human side, there is no scientific evidence to suggest that vaccinations lead to autism,” Liff said. “So it’s far-fetched to drag that into the veterinary practice —because autism doesn’t even exist in pets.”
