Part of ensuring that your dog is healthy is taking care of fleas as soon as you see them. While you could target each individual flea you spot using a special flea comb, this is incredibly time-consuming and won’t necessarily remove the eggs as well as adult fleas. You are much better off finding a best flea killer for dogs at the first sign of these pests. If left alone, a single flea can easily turn into dozens or hundreds in no time at all. Don’t put your dog’s health at risk and instead invest in an effective flea killer. Now you just have to figure out which one you should buy. The following information will get you started.

What You Need To Consider

Because flea killers contain chemicals, you should always do your research carefully before buying one. Keep the following factors in mind when choosing the best flea killer for dogs.

  • Oral Medicines

A popular type of flea killer is an oral medication. These tend to be effective and easy to use as you just need to get your dog to swallow it. Certain oral medications do have side effects, however, so always read the instructions and cautions before buying.

  • Spot Treatments

Spot treatments are the most popular type of flea killers for dogs and also tend to be preventative. These treatments are placed on your pup’s neck where he can’t reach and will usually last at least a month, if not several. They are highly recommended by vets.

  • Shampoos

For pooches that are heavily infested, the best flea killer for dogs will be a shampoo. These are used just like any other dog shampoo, but typically require extra care around the eyes and face in general. With a flea-killing shampoo, you will see the bathwater filling with dead fleas in no time. Just keep in mind that the effects of a flea shampoo don’t typically last as long as those of a spot treatment or oral medication. Because of this, the shampoo is best used in combination with other treatments or as a first step in severe cases.

  • Collars

Perhaps the simplest type of flea killer you will find is a medicated collar. These collars concentrate the active ingredients in one of the most popular spots for fleas to hide, the neck. Despite being in this one spot, they still effectively kill fleas all over your dog, provided you choose a collar of the right size. Collars typically last at least a month to several months, slowly releasing the active ingredient over time.

  • Kills Eggs As Well

When looking at a flea killer ensure that the product not only kills the adults, but takes care of the eggs as well. There are several insecticides known as growth regulators that stop fleas and other insects from finishing their growth cycle and turning into adults. Ingredients like methoprene or pyriproxyfen are growth regulators that you should look for in the ingredient list. Remember that a single female flea lays between 20 and 40 eggs each day; killing the eggs or stopping them from growing is crucial.

  • Kills Other Pests

Most flea-killers will also kill ticks, but you should double check. You should also be able to find a product that kills lice, mites, mosquitos, and other pests if this is important to you.

  • Also Preventative

The vast majority of flea-killing products you find will also work as preventative tools to keep fleas away, but you should also confirm this is the case. After all, you don’t want to rid yourself of all the current fleas just to have the problem repeated.

  • Natural Or Chemicals

Most of the highest-rated flea killers for dogs will contain chemicals such as insecticides that are safe for canines. If your pooch has sensitive skin or you simply don’t like using chemicals, there are some natural alternatives available as well. When choosing a natural flea killer, be extra sure to read reviews as these may or may not work as well as chemical-based treatments. The right natural solutions will be as effective, but there are also many natural products that don’t live up to their claims.

  • Age And Weight Requirements

Almost every single flea killer you find will be designed for dogs that are at least seven or eight weeks old as the chemicals used are too strong for young puppies and can be harmful to their health. If your dog is still young or is very old, pay attention to the age requirements for the product.

Flea killers also have weight ranges in which they are effective. Choosing a medication designed for a pooch that is too large will provide an excessive amount of chemicals that can be harmful for your canine. If you choose a product with a weight range too small for your dog, the treatment may not be effective. Because of this, you should always follow the instructions for dog weight.

  • Do You Have Cats?

Even if you use a different product on your cat than you do on your dog, you should avoid anything with pyrethroids or amitraz on your canine if you have both types of animals. These chemicals are so toxic to cats that even if they rub next to a pooch that was recently treated, they can get sick.

  • Safety For People

When choosing the best flea killer for dogs, make sure that it is safe for use around people, especially if you have young children. With most products, there is only a risk of coming in contact with insecticides or other chemicals for several minutes after application (in the case of topical medications). Don’t choose a product that has an ingredient which is toxic to pets or humans as you want to be able to touch your pooch following application.

Conclusion

Any of the above options will give you a best flea killer for dogs that should provide relief for your pooch in days, if not hours. You can even sometimes combine methods, such as a flea-killing collar with a spot treatment, to get better results. No matter which product you choose, make sure to choose quickly as you want to minimize your pooch’s suffering.
