Left untreated, fleas can multiply rapidly and make your dog seriously ill. That's why it's important to check your dog for fleas on a regular basis and act quickly to eliminate any outbreaks that occur. Some dogs are severely allergic to flea saliva and can experience extreme discomfort even from a single flea bite.
Do fleas eventually go away?
Will Fleas Go Away on Their Own? The short answer is no, they won't! Fleas feed and reproduce on dogs, cats, and other pets with substantial hair, fur, or feathers. They are parasites that need blood hosts to survive, so they will jump around all the potential hosts in your home to find one.
How long can fleas be left untreated?
Without a host, adult fleas live only a few days to 2 weeks. On short-haired cats and dogs fleas survive an average of 8 days; they live longer on long-haired animals.
What happens if you don't treat fleas on cats?
All cats are irritated by fleas, but some cats are so hypersensitive to flea saliva that they can suffer an allergic reaction. If left untreated, this can pose some serious health risks. And fleas, don't forget, are bloodsuckers. If your cat is young or frail, losing too much blood to fleas can be fatal.
Can fleas kill a human?
And in 2015, a teen reportedly died from contact with fleas infected with bubonic plague. Now, fortunately, fatal fleas are pretty rare, and most likely it'll be your pets, not you, that have to deal with them. But if you do see one or two jumping around, you definitely should try to get rid of them.
