Constant Scratching

Constant scratching is the most obvious symptom of a dog that has problems with fleas. A dog without an allergy is most likely to have visible fleas and eggs on its body in a fatal infestation. If flea bites are left untreated it leads to intense scratching that can cause lesions on the skin and open sores and finally become infected.

Allergic Reaction

To remove visible fleas and their eggs from the skin you can flea comb.

Some dogs are very sensitive to flea saliva that contains a lot of bacteria and can have an allergic reaction after being bitten. This type of dog will develop much worse sores on the skin than average and, as a result, be more susceptible to infection.

If not treated, these infections can be fatal. Redness accompanied by puss around the area, hair loss, and fever are the signs and symptoms of infection.


Anemia is the most common cause of death from flea infestation. This condition occurs if there is a shortage of red blood cells – according to PetMD. And according to the ASPCA, a flea can consume blood up to 15 times its body weight. So, thousands of fleas together can consume a significant amount of the dog’s blood.

Anemia in a dog can be determined by a blood test and a bone marrow test may be conducted to determine the causes. Small dogs and young puppies are more likely to and at the highest risk of developing anemia.
