Somehow Heidi's question has triggered my flea center. What Heidi needs to do is eliminate the source of the scratching. It is discouraging how many animals I see that are suffering from flea infestations. It requires money, toxins and work, but my pets' skin and digestive tracts are worth it. It simply is mind boggling how many times a day we vets administer tapeworm medications, anti-inflammatories and antibiotics to animals whose problems would be best solved by having owners willing to effectively deal with the fleas.
Fleas are the most common cause of skin problems in animals.
Dermatitis and secondary infections range from mild to very severe. Reducing flea numbers is sometimes a daunting task, yet with diligence it can be done. If you are sucessful in this, the skin can take care of itself in most cases. In the long run it is better for your pet than scratches, allergies, tapeworms and trips to the vet. While much interest has been expressed, no one has of yet posted any solid information.
