Prevention and Treatment of Fleas
Flea prevention is much easier than eradicating many tiny fleas and their offspring from your dog and your home. There are several things you can do to prevent fleas, Evans says.
“The best, safest and most effective way is to use a prescription product from your veterinarian,” she says. “The over-the-counter medications can cause serious reactions and rarely ever actually work well. The prescription products are much safer and are fully effective. You can also prevent fleas by keeping your pet away from flea infested areas, but this is difficult because you can't always know what areas are infested with fleas.”
If your dog already has fleas, Evans recommends, putting all the dogs and cats in your home on an effective flea prevention product from your veterinarian, vacuuming your whole house (including upholstered furniture), laundering all pet and human bedding, and consulting with outdoor professionals to see what should be done to minimize fleas in your yard.
