Welcome to the discussion on whether fleas have to bite for Nexgard to work. Nexgard is a popular flea and tick medication used to keep our furry friends safe from infestations. However, there is often confusion when it comes to whether fleas have to bite our pets for Nexgard to be effective. In this discussion, we will explore the mechanics of how Nexgard works and answer this common question.
Understanding Fleas and Nexgard
Fleas are a common household pest that can cause irritation and discomfort for both humans and pets. These small, wingless insects feed on blood and can quickly multiply if not addressed promptly. Nexgard is a popular flea and tick preventative medication for dogs that comes in the form of a chewable tablet. But do fleas have to bite for Nexgard to work?
The Role of Flea Bites in Nexgard’s Effectiveness
The short answer is no, fleas do not have to bite for Nexgard to work. Nexgard contains an active ingredient called afoxolaner, which is an insecticide that targets the nervous system of fleas and ticks. When a dog ingests Nexgard, the afoxolaner spreads throughout their bloodstream and is then released through the skin’s oil glands. This means that any fleas or ticks that come into contact with the dog’s skin will be exposed to the insecticide and killed, without having to bite the dog first.
How Nexgard Works to Keep Your Dog Flea-Free
Nexgard works by disrupting the central nervous system of fleas and ticks, causing paralysis and death. The afoxolaner in Nexgard binds to specific receptors in the insects’ nervous system, causing prolonged hyperexcitation that leads to their demise. This means that even if a flea or tick has not yet bitten your dog, they will still be killed upon contact with the dog’s skin.
The Benefits of Nexgard
Convenient and Effective Flea Prevention
One of the main benefits of Nexgard is its convenience. Unlike topical flea treatments that can be messy and time-consuming to apply, Nexgard is a chewable tablet that can be easily administered to your dog. It is also effective in preventing both flea and tick infestations, making it a great option for pet owners who live in areas with high tick populations.
Long-Lasting Protection
Nexgard provides long-lasting protection against fleas and ticks, with a single dose lasting for up to 30 days. This means that you only need to administer the medication once a month, making it a convenient option for busy pet owners.
Safe and Effective
Nexgard is a safe and effective flea and tick preventative medication that has been approved by the FDA for use in dogs. It is also effective in killing fleas and ticks that have developed resistance to other insecticides, making it a great option for pet owners who have tried other flea treatments without success.
Common Misconceptions About Flea Prevention
Myth: Fleas Only Affect Dogs During the Summer Months
Many pet owners believe that fleas are only a problem during the summer months when temperatures are warm. However, fleas can survive and reproduce year-round in indoor environments, making them a year-round problem for dogs.
Myth: Flea Collars Are the Best Way to Prevent Fleas
Flea collars are a popular flea prevention method, but they are not always the most effective. Many flea collars only protect the area around the dog’s neck, leaving the rest of their body vulnerable to flea infestations. Additionally, some flea collars contain toxic chemicals that can be harmful to pets and humans.
Myth: Natural Flea Prevention Methods Are Always Safe and Effective
While natural flea prevention methods can be effective, they are not always safe for pets. Essential oils and other natural remedies can be toxic to dogs if ingested or applied improperly. It is important to speak with your veterinarian before using any natural flea prevention methods on your dog.
