When used as directed it is safe for all breeds of dog and cat. Fleas are a fact of life for your pet and are very irritating and hard to control. Left untreated fleas can quickly multiply. A flea will lay up to 50 eggs per day and can start to lay in as soon as 48 hours on your pet. The eggs are laid on your pet and drop off in your pets living areas particularly its bedding where they can quickly develop into new adult fleas.
Fleas are the most common cause of skin disease and also are the source of the common tapeworm.
Program has been scientifically developed as a once a month treatment for fleas. When the adult flea bites your pet it takes in a dose of program and the program works on the female flea by killing the flea eggs before they hatch. This inability of the flea egg to hatch means the normal build up of the flea population is stopped. Because Program does not kill the flea it is important to use a product that will kill any fleas getting on your pet while Program is doing its job. These flea killing products can be flea rinses, shampoos, sprays or powder.
