Best Dog Flea Drops Buying Guide

Before choosing the best dog flea drops you should consider following options:

1. EPA-Approved Brands: All EPA-approved brands contain an active ingredient that kills adult fleas. These include fipronil, which kills fleas within 15 minutes of contact; and methoprene, which kills fleas on contact but also sterilizes them so they cannot reproduce.

The EPA requires that flea drops be applied to the back of the neck, where the skin is thin and absorbent.

2. New-Generation Drops: New-generation flea drops, such as those containing nitenpyram and lufenuron, are a good choice for dogs that spend time in areas where fleas are endemic, such as wooded areas.

Nitenpyram kills adult fleas and prevents flea eggs from hatching for up to 30 days. Lufenuron, which is a larvacide, breaks the life cycle of fleas by preventing newly hatched flea larvae from maturing into adults.

3. Safety: Flea drops are safe, as long as they are used according to the directions on the label.

If your dog has a bad reaction to a flea drop, you can bathe him with a flea-control shampoo and then reapply the drop.

4. How Long the Effect Lasts: When choosing flea drops, it is important to find out how long the effect will last. Some products kill fleas within hours, while others last up to a month.

5. What the Ingredients Are: Not all ingredients are safe for all dogs, so it is important to read the label and make sure it is appropriate for your dog.

Some flea drops contain lufenuron, which is not safe for dogs with a history of heartworm. Flea drops containing fipronil may not be safe for dogs weighing less than 8 pounds or puppies less than 2 pounds.

6. Price: Flea drops range in price from $7 to $15 per dose, depending on the brand and the size of the dog.
