Why year-round prevention in LA
Los Angeles never gets cold enough to stop fleas, and the mosquitoes that carry heartworm are active much of the year. Heartworm disease has been diagnosed in dogs and cats across Southern California, and treatment for dogs is long, expensive, and hard on the body. For cats, there’s no approved treatment at all; prevention is the only protection. Missing a month leaves a gap that larvae can slip through.
Which product is right?
It depends on your pet’s species, weight, lifestyle, and health history. Some products cover fleas and ticks only; others add heartworm and intestinal worms. We’ll help you choose, then you can order through pprx.vet, our online pharmacy, and have it shipped to your door. Already using a product? Use this tool to stay on schedule.
Common questions
What happens if I miss a heartworm dose?
Give the next dose as soon as you remember, then call us. If more than a couple of weeks have passed, the American Heartworm Society recommends heartworm testing, because a gap allows larvae to mature. We’ll tell you exactly when to test.
Do pets in Los Angeles need flea and heartworm prevention all year?
Yes. LA’s mild climate lets fleas survive year-round, and heartworm has been diagnosed throughout Southern California. The American Heartworm Society recommends year-round prevention for all dogs and cats.
Do indoor cats need prevention?
Yes. Fleas ride in on clothing and other pets, and mosquitoes get indoors. In one study, about a quarter of cats diagnosed with heartworm were described as indoor-only.
Where can I buy my pet’s prevention?
Order through pprx.vet, our online pharmacy, for delivery to your door. Prevention requires a current prescription from a vet who has examined your pet.
