Revolutionand Frontline Plus are two good flea products to consider for tiny dogs. Revolution protects dogs against fleas, heartworms, ear mites, sarcoptic mange, and some ticks. It is applied to and absorbed through the skin and should be given once a month. Revolution is available for pets under 5 pounds, for those between 5 and 10 pounds, and for larger individuals as well. Revolution is labeled for use in dogs that are six weeks of age and older and requires a prescription from your veterinarian.
Frontline Plus is a monthly topical product. It does not prevent heartworm disease, so an additional medication to protect against this serious condition will also be needed. The smallest dose formulation of Frontline Plus is labeled for dogs 0-22 pounds. Frontline Plus is safe for use in animals eight weeks of age and older.
