Fleas aren\u2019t just annoying for dogs. These small blood-sucking parasites can cause serious health issues, including spreading tapeworms (to pets and humans) and causing anemia in the case of a severe flea infestation. Fleas are good at avoiding detection, but there are signs that you can look for, including flea dirt and excessive itching.<\/p>\n\n\n\n

Signs of Fleas on Dogs<\/h2>\n\n\n\n

It\u2019s a scary thought, but only around 5 percent of dog fleas are actually adult fleas \u2014 the rest are in various stages of the flea life cycle (eggs, larvae and pupae). The immature\u00a0flea life stages\u00a0can be found in the cracks between hardwood, laminate or floor coverings, in bedding or upholstered furniture. Eww!<\/p>\n\n\n\n

Fleas are hard to find, but if your dog has fleas, you may notice that they are itchy and more restless than usual, and are licking, scratching or chewing (like they\u2019re eating a corn cob) in specific areas. Other symptoms include hair loss or bald spots due to the excessive licking and chewing, and your dog\u2019s skin may be bumpy from all of the scratching.<\/p>\n\n\n\n

Can You See Fleas on Dogs?<\/h2>\n\n\n\n

When you look for fleas on your dog, you need to be quick since fleas move fast and can be hard to spot. These tiny parasites are only 1\/16 to 1\/8 inch tall and are dark brown, although they become lighter in color as they start to ingest blood. Typically, you can only spot fleas easily if a dog has a severe flea infestation.<\/p>\n\n\n\n

If you suspect your dog has fleas, check the armpits and groin first. Adult fleas love to hide in these areas because they are warm and protected. Next, check your dog\u2019s tummy, where the hair is usually thinner and fleas are easier to spot.<\/p>\n\n\n\n

How to Tell If Your Dog Has Fleas<\/h2>\n\n\n\n

As we mentioned, fleas themselves can be hard to spot in typical cases, so an alternative is to look for flea dirt (flea droppings) which are dark specks of digested blood that look like pepper on the dog\u2019s fur or skin. Using a flea comb, collect the suspected flea dirt and place it on a wet, white paper towel. If it is flea dirt, the digested blood in the flea feces will turn the paper towel red.<\/p>\n\n\n\n

What Do Flea Eggs Look Like on a Dog?<\/h2>\n\n\n\n

Flea eggs are even harder to spot than adult fleas on dogs, especially if your dog has light-colored fur. They are tiny, whitish, oval-shaped specks that resemble a grain of salt. If you do see some, you might think flea eggs are just dried skin flakes.<\/p>\n\n\n\n

Dog Flea Bites Can Cause Allergies<\/h2>\n\n\n\n

Fleas are one of the most common causes of allergies in dogs, and the trouble can start from just one flea bite. Some dogs are allergic to flea saliva and can develop flea allergy dermatitis (FAD) from flea bites. For\u00a0dogs with FAD, skin reactions are often seen along their lower back, thighs, lower abdomen and forelegs. All of the licking and scratching can irritate the dog\u2019s skin and create openings where bacteria and yeast can enter, leading to secondary infections.<\/p>\n\n\n\n

If your dog has flea allergy dermatitis, it is critical to eliminate fleas with a flea treatment and use medications to prevent fleas from reinfesting your dog in the future. Dogs with FAD may also need other treatments to soothe irritated skin and treat secondary infections.<\/p>\n\n\n\n

How to Treat Fleas on Dogs<\/h2>\n\n\n\n

If your dog has fleas, purchase a flea comb that is specifically designed to remove fleas, as well as flea larvae and eggs, from your dog\u2019s coat. Brush your dog\u2019s fur, making sure to brush as close the skin as possible to capture the fleas. As you\u2019re combing, get rid of any fleas you find by dunking the comb in a bucket of soapy water. Some flea infestations may also need prescription medication or medical shampoos to kill the fleas. And because fleas are also in your dog\u2019s environment, don\u2019t forget to treat the inside of your home as well. It can take three or more months to completely rid a home of fleas.<\/p>\n\n\n\n

Year-Round Flea Prevention Is Key<\/h2>\n\n\n\n

Fleas may be most active in warmer months, but they can remain a problem throughout the year in many regions. Along with\u00a0topical, oral, collar or other preventative flea medications\u00a0for your dog, there are some simple things you can do around the house to get rid of fleas and prevent a flea infestation.<\/p>\n\n\n\n
