NexGard Approved to Prevent Lyme Disease Infections for Dogs

FDA Approves NexGard Chewables for prevention of infections that cause Lyme disease in dogs

The U.S. Food and Drug Administration has approved NexGard to prevent Borrelia burgdorferi infections by killing Ixodes scapularis, a type of Black-legged tick that carries the bacteria. The Borrelia bacteria is an infectious bacteria that causes Lyme disease in dogs. The black-legged tick is also known as the deer tick. Lyme disease can cause serious illness in both animals and people. Fever, loss of appetite, lameness, joint swelling, and lethargy are common warning signs in dogs. In severe cases, Lyme disease can affect the kidneys, nervous system, or heart. Learn more about Lyme disease on our blog.

NexGard Chewables at VetRxDirectNexGard is a prescription flea and tick preventative for dogs that contains afoxolaner. This medication works by absorbing into the dog’s bloodstream to treat and prevent flea infestations and kill ticks. It is effective against the Black-legged tick, American Dog tick, Lone Star tick, and Brown dog tick.


NexGard is formulated to give protection for 30 days and is a soft, beef-flavored chew. Dogs can also be bathed or swim at any time because it is given orally and does not create a residue on the skin or hair coat. It is also designed for safe administration alongside heartworm and other medications. NexGard chewable can be given to dogs 8 weeks of age and older and weighing 4 pounds or greater. It is available in four sizes: 4-10 lbs, 10-24 lbs, 24-60 lbs, and 60-121 lbs and three, six, or 12-month quantities.

⭐⭐⭐⭐⭐ Convenient     

My golden had Lyme disease a few years ago and this product, Nexgard, has kept her protected. We have a large deer population in our neighborhood and I feel confident using Nexgard

⭐⭐⭐⭐⭐ Works great!

My German shepherd is 2 years old and he has yet to get a tick because l have given him nexgard since he was a puppy.

⭐⭐⭐⭐⭐ Awesome, fast results

We have been having such a difficult time with ticks this year even though we’ve been using both a topical treatment along with a Seresto Flea collar. Our golden retriever has been on NexGard since the beginning of the month and we are thoroughly pleased with the results, not 1 flea since we started and no itching either. We’ll definitely continue to use both VETRX Direct and NexGard, I highly recommend it.       -Submitted by   Kim ✅ Verified Buyer
