The 5 Best Pet Flea Medications

ShareThis

Flea and tick bites can cause your pet discomfort and unhappiness. If left untreated, your pet can contract a number of illnesses, such as flea allergy dermatitis, skin infections and irritation, anemia, and even tapeworms. That’s why it’s important to treat infested areas as soon as you notice a problem to stop the flea life cycle.

What Is Pet Flea Medication?

Pet flea medication can be applied to your pet on a monthly basis to kill fleas, ticks, and other pesky critters that may be harming your pet. You’ll want a flea medication that works quickly and effectively, is easy to use, and will last about a month per dose. Keep in mind that your pet may still temporarily scratch as a result of the fleas dying.

Remember, it’s important to always use dog products on dogs and cat products on cats. They cannot be used interchangeably, even if you choose a natural product. However, if the medication specifically states that it is safe for both cats and dogs, then you can use them on all of your furry pals. Even if a medication claims to be completely safe for your animal, each pet is different and yours may not react well. If you notice any problems or signs of lethargy or discomfort after using a flea medication, contact your vet.

If you need further protection from fleas and ticks, consider something like the bestselling Vet's Best Flea & Tick Home Spray or the bestselling Vet's Best Flea & Tick Yard & Kennel Spray.
