When it comes to canine health, many pet parents understand the benefits of a balanced diet, and regular exercise.

Fleas and ticks on your dog are more than just a nuisance; they can often result in parasitic diseases and infections to both humans and animals because of their bites and the scratching of their persistent itches.

From kennel and carpet sprays to powders and room foggers, you are bound to find the right flea treatment product for all of your dog’s favorite hang outs. You can also add to their protection through monthly topical or spot-on treatments. Regardless of their breed or size, you’ll find an array of flea medicines and treatments for dogs that offer options based on their weight and life stage.

Pups who spend the majority of their time outdoors are at even greater risk of needing flea treatment for dogs. Regular use of sprays and mists specially formulated to repel fleas, ticks, mites and many other common parasites can help prevent the spread of fleas for dogs. When used in and around your yard and dog house, the risk of infestations can be decreased when these pests are in season. Keep your pup and home happy, healthy and protected through effective flea medicines and treatments for dogs available at Petco.
