Buying Guide

Flea preventative treatments are essential, such as getting a flea collar. They can help ensure that your dog is protected against fleas and some of the more serious issues that can be associated with getting fleas. You will want to be sure that you select the right product for your dog, so read through our buying guide to help you make your selection.

Weight

It is very important to select a flea treatment that includes your dog’s weight. Look closely at each option, since some are designed for large dogs and some are designed for small dogs. You want to be sure you choose a product that will provide enough coverage for your dog’s size, without being too much.

Length of Protection

Next, look for how long a dose of treatment should continue to work. Many products will provide protection for 30 days, but some may be more or less, so be sure to look closely before making a purchase. You should also pay attention to how quickly the product will start working and providing protection for your dog once it is applied.

Other Parasites Covered by the Treatment

Another key thing to look for is what other parasites will also be killed or prevented by the flea treatment you select. Some flea treatments will also provide protection against lice, mosquitoes, or ticks. If these are common problems in your area, or you just want to be extra precautions, look for a treatment that will also get rid of these other parasites.

Type of Treatment

Some flea treatments are liquids that you apply to the back of your dog’s neck, while others are oral treats or pills. Both are effective, so you can use other factors to help you decide which option you’ll prefer.

If your dog is a picky eater or hard to give a pill to, you may decide to choose a liquid treatment. If you have young children that won’t be able to avoid touch the back of your dog’s neck for a while after the treatment has been given, a pill or treat option may be the best fit for your needs.
