One of the most conspicuous signs of fleas are what they leave on your dog. Take a close look at your dog’s skin to see if they have any small, red, raised bite marks. Additionally, fleas often leave behind “flea dirt,” which will look like small, dark grains of sand, as well as small white eggs that resemble tiny grains of rice.  If your dog has an allergic reaction to the bite, the red area may be larger. If your dog has dark fur, run a flea comb once through its fur to check for signs of fleas. Then, tap the comb on a white paper towel to see if any flea dirt or eggs fall off. Excessive scratching, licking, and biting at the skin is another clear sign your dog may have fleas. Watch your dog’s behavior to see if they are suddenly itching, biting, or licking at their skin more than is typical. Scabs, bald spots, and inflammation can be indicative of a number of skin conditions, including fleas. If you suspect fleas, take a look at your dog’s coat to see if the they have any areas of irritation, bald spots, or scabs. If you find any of these symptoms present on your dog, call your vet. In addition to being a sign of fleas, these symptoms could be signs of ticks, mange, and other canine skin conditions. In severe cases, you may actually see adult fleas jumping on your dog’s back when it moves. Take your dog to the vet right away for treatment. The severity of the case also depends on your dog, so don’t panic. The vet will be able to tell you how bad it is and prescribe treatment accordingly.
