Love how she eats it with ease so I assume it doesn’t taste bad . Comes with stickers to mark on calendar when next dose is due so you never forget !

    We needed the Nexgard in Florida for our little Taz. We live in a part of Colorad that has no fleas. It was important to us to have it there when we arrived. It was and all is well for Taz and his family.

  • Allergy caused itching gone!!

    By on

    My Maltipoo was diagnosed with “environmental allergies” because of her constant scratching. She doesn’t have fleas so I was surprised when the vet recommended that she get monthly Nexgard!! The vet told me it had stopped her dogs scratching from the same thing. Ever since that first dose, there has been no scratching! And my dog loves it. My daughter gave the Nexgard a try for her small dog and it worked to stop the scratching with the first dose!!

    My 5-lb Yorkie loves it and has no side effects from it. This was delivered faster than expected. I ordered 2 6-packs so I would have a 1-year supply and was worried about the expiration date. It was beyond one year on both boxes so I am very happy.

  • Much Easier

    By on

    These chews are so much easier to give to my dog than trying to put the topical on him. He hates the topicals, and I always felt so guilty putting it on him because he'd run around like crazy after trying to rub it off. With the chews, he thinks it's a treat, so he's excited to get them!

  • NexGard Chewable Tablets for Dogs, 4-10 lbs

    By on

    Within an hour of administering the tablet fleas were coming to the surface of my pets hair. Reading the FAQ section states that this is normal as the medicine is impacting the fleas nervous system. The fleas were almost dead at that time and were easily picked off and discarded. However, the dogs do still scratch and its been 8-days...but I haven't seen any fleas on the dogs or in the house. Maybe they're just scratching previous bites.

  • Best I’ve used

    By on

    I once had gotten fleas even though my dog was already on front line topical each month. The vet recommended this. Worked amazing! Fleas were gone by the next day. And I’ve been using this ever since and never had any more issues with fleas. My dogs love the taste and never had any bad reactions either. Win win for me.
