Bad side effects

I want to file a complaint and get a compensation due to the horrible side effect, none stop diarrhea, that our dog now has! He was taking this medicine for 3.5

I want to file a complaint and get a compensation due to the horrible side effect, none stop diarrhea, that our dog now has! He was taking this medicine for 3.5 years and last time when we gave it to him totally destroyed his digestive system and stool. Nothing else changed in his daily routine that could have led to that, except this new package of medicine we have him with his meal. He has diarrhea at home (which he never had!), he can't hold his poop, we have to take him outside several times during the night! He is suffering and it doesn't go away. If someone from the manufacturer doesn't get back to us, I will start a lawsuit.

Outstanding Customer Service

This was my first time filling a prescription at Chewy's and I had questions that needed answers and, then, some issues with getting the prescription to Kentucky

This was my first time filling a prescription at Chewy's and I had questions that needed answers and, then, some issues with getting the prescription to Kentucky. I had to make two separate calls and each representative I spoke with was polite, knowledgeable and took all the time necessary to get my mailing issue sorted out. It was so refreshing to, first, talk with a human being and then get my needs met in a timely manner. I learned a lot from their staff which will hold me in good stead for my future putchases. Truly wonderful people at Chewy's. Highly recommended!!

NexGard WORKS

I am so thankful and relieved to have finally tried NexGard, just when I thought NOTHING would work on the fleas on my dog here in Florida. My dog is 16 years old

I am so thankful and relieved to have finally tried NexGard, just when I thought NOTHING would work on the fleas on my dog here in Florida. My dog is 16 years old (!) and has been suffering from an intractable flea infestation for 3 or 4 years, poor thing--I tried everything during that time: Bravecto (used to work, before that, but stopped working about 4 years ago and does not work at ALL), treating the house with natural things (didn't work at ALL), Advantage II (cut down the load of fleas, so at first, I thought it was working, but still, my dog had a bad infestation), and Capstar (works but only last for 2 days). Finally, two months ago, I got him on NexGard. It worked IMMEDIATELY, but I didn't trust it, so I waited to write this review until a whole month went by, which now it has, and my dog is currently sleeping peacefully and comfortably by my side, after getting his 2nd monthly dose yesterday. He has ZERO fleas, ZERO flea dirt, and his chewed up hot spot is healing beautifully. I give him his pill in a little ball of pure, soft goat cheese, wrapped in some "shaved beef", both from Trader Joe's. He loves that "treat" and eats it right up. I also got my two cats on a new flea product (Credelio) at the same time, which the vet recommended (the vet also recommended the NexGard for the dog, as did a neighbor and another friend here in Florida who use it). Again, I can't emphasize enough that NexGard is the ONLY product that works anymore for the particular fleas (whatever type they are!) that were (thank goodness it is finally past tense!) on my dog here in Florida. And again, he is 16 years old, so very senior, and is not experiencing any side effects--other than no fleas, which is the effect we wanted, yay!

I do not get the best price as auto ship order. I just do not have the time right now to research it. It's a shame you have to continually check prices instead of getting the best $$$ on an auto ship order. You would think repeat customers would get the best, but apparently not.

We switched from another oral flea and tick medication. Our dog would refuse it. She would sniff it out of anywaI tried to camouflage it. I would have to force it down her throat. It was horrible. Switching to Nexguard, she eats it up instantly. So happy we switched. Wish I would have done it sooner.
