Why treating fleas is so important

Not only is the presence of fleas a nuisance for your pet, your family, and your home, but fleas can also lead to diseases for your furry friend.

Flea allergies are truly awful

Fleas are the #1 cause of allergies in pets. Pets can develop a severe allergic reaction after even a single flea bite causes their immune system to react. Also known as flea allergy dermatitis, it causes extreme itchiness. Constant scratching may cause skin issues, which can then easily lead to skin infections.

The best form of treatment is year-round flea control — either topical or oral.

Fleas carry tapeworm larvae... yum

Fleas can go right down your pet’s gullet if your pet accidentally eats one. This is especially problematic for cats who clean themselves by licking. Any tapeworm larvae the flea carries can then settle in your pet’s intestines, where it sucks out nutrients and sheds segments into pet poo.

The easiest way to avoid that unpleasant experience for you and your pet? Start and keep them on year-round flea control meds.

Fleas can lead to blood loss and anemia

Fleas can consume 15 times their weight in blood a day. Multiply that by a serious flea infestation and you’re talking life-threatening blood loss. Kittens and puppies are at special danger of losing too much blood to flea infestations, while even grown pets can suffer from flea-related anemia, or low red blood cell counts. Signs of flea-related anemia include pale gums, lethargy, loss of appetite, and weight loss.

Get your pet on a vet-recommended flea control product to avoid the risk of flea-related anemia and blood loss.

Fleas can affect people too

While not super common, fleas can spread diseases to humans as well. These include tapeworm from accidentally swallowing an infected flea and flea-borne typhus from scratching an infected bite.
