Can Fleas Become Immune to NexGard?

There are many benefits of flea and tick prevention, including the prevention of Lyme disease and other illnesses that can be caused by infestations. NexGard is one of the most popular flea and tick preventatives, and it can help prevent your dog from contracting these diseases. However, it is not without side effects. Some dogs may react to the active ingredient, afoxolaner, and experience allergic reactions. In those cases, it is important to consult with your veterinarian. The veterinarian can prescribe alternative flea and tick prevention methods to help keep your dog safe from parasites.

Despite its effectiveness, there is a chance that fleas can become resistant to Nexgard. Although this phenomenon has never been documented, it is a likely occurrence, especially with some of the most popular products. Resistance to these products may occur over time, especially if human error is involved. For this reason, it’s important to treat every household pet regularly with an effective flea prevention product.

NexGard is an FDA-approved chewable pill for dogs. It is also more convenient than the topical option, which can leave your dog with a lot of greasiness and is much easier to administer. If you’re concerned about the side effects of Nexgard, don’t hesitate to consult with a veterinarian.
