The Best Flea Treatment For Dogs

1. Frontline Plus

There are topical flea treatments that you can apply to your dog once a month. These treatments will usually last for a few weeks and protect your dog from fleas. Some of these treatments also work against ticks. The effectiveness of the treatment and how well dogs tolerate it depends on its active ingredients.

Frontline Plus is a veterinarian-recommended flea and tick treatment known for being effective and easy to use. Dogs are also well-tolerated, making them a great choice for anyone looking for a reliable solution.

Frontline Plus is a monthly liquid that kills fleas and ticks for 30 days. It contains two active chemicals that destroy fleas, ticks, and their eggs and larvae. If your dog doesn’t like to be bothered, the once-a-month dosage is good.

Frontline Plus begins killing fleas four hours after it is applied, and it kills 100% of the fleas on contact within 12 hours. However, the chemicals in Frontline Plus are hazardous to humans, so it is important to avoid touching the dog if you have recently applied it. Application of Frontline Plus on dogs with long-hair coats can be more difficult than on smooth coat pups, as it is important to get the solution close to the dog’s skin.

Advantix is a more effective insecticide than Frontline, killing mosquitos, lice, and fleas, as well as ticks. However, it is also more expensive – up to 30% more than Frontline Plus. To determine if the extra protection is worth it, you must consider your surroundings and how frequently your dog encounters mosquitoes or lice.
