Benefits vs. Side Effects

There are many benefits to using flea prevention in pill form. Pet owners do not have to worry about exposing their family to insecticides, diminishing effectiveness by washing the pet or the pet shaking the medication off onto the floor or furniture.

Although very rare, vomiting, diarrhea, lethargy and depression are the most commonly seen reactions, and a veterinarian should be consulted immediately if you believe your pet is having a reaction to either oral or topical medications. Read the accompanying information included in the packaging and follow all instructions when using flea medicine for dogs. If you have any questions or concerns about using a product, talk with your veterinarian so that he can provide more detailed information.

Flea prevention and control is a benefit not only to the pet, but the entire family. Fleas do carry disease, many of which are transferable to both pets and humans. They can also be very harmful to your pet's health, by causing many different types of issues including anemia and in severe cases, even death.

The best control of fleas comes from prevention. When you first bring a new pet into your household, talk with your vet about which medication is best suited for your pet's needs. Controlling the situation and never allowing a problem to manifest will be the easiest solution for both you and your pet.
