Fleas feed on blood and therefore bite the host to the point of bleeding. The fleas then suck up the blood. Some dogs and cats can have allergic reactions to the flea’s saliva, causing intense itching and scratching.
What do Flea Bites Look Like?
Flea bites can look a lot like mosquito bites or little red welts. If your pet is suffering from a bunch of flea bites it is a good idea to bath him with a gentle shampoo to help soothe the bites. I like to use a peppermint tea tree oil shampoo for dogs and an unscented shampoo for cats. I recommend unscented shampoo because cats are sensitive to essential oils.
