Only bad thing is I wish I had tried this sooner

My pomchi Bailey Hope has had a severe flea allergy(even if she has just 1 or 2 fleas)that has been a huge issue for the last yr & figured I just needed to keep

My pomchi Bailey Hope has had a severe flea allergy(even if she has just 1 or 2 fleas)that has been a huge issue for the last yr & figured I just needed to keep treating with the usual brands + spray my yard, bathing etc. Shes been so itchy & I was going thru baby Benedryl to help. The cost was really the main reason I didnt buy this brand & didnt really think it would make that much of a difference. However today, after about 3wks since her 1st treatment I realized I havent had to give her any Benedryl for almost a wk give or take. Will keep using it. Definitely recommend, esp if your fur baby has allergies to fleas!

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!

They contacted my vet for the prescription for the flea medicine. I have it on auto ship. It was it will ship in one year that’s very convenient. I ordered it and received it in a couple days. I had a problem with something on my order. I called them, they answered my question in seconds very friendly. I have never had such a good company ever. They have fast friendly service. I will tell everyone about Chewy. This was also on a Saturday.

Flea medicine

Our pit has been on this medication since we adopted her 3 years ago. So when we adopted Whiskey we put him on this. We don’t have nothing negative to say about

Our pit has been on this medication since we adopted her 3 years ago. So when we adopted Whiskey we put him on this. We don’t have nothing negative to say about this medication. When we adopted him he had fleas. Medication killed them all. He was in bad shape when we got him. His fur was falling out due to a fungal infection. He is all good now living his best life. He is 4 mths old.

Don’t hesitate-worth every penny

I never review products however I truly believe there are some things that need honest reviews, especially when they are slightly Pricey and extremely important

I never review products however I truly believe there are some things that need honest reviews, especially when they are slightly Pricey and extremely important. I felt this is one of those times. I have two small dogs that just moved with me from NY to NC. Rocky is 13 and Daisy is 10, never in their lives have either of them taken or needed flea/tick medication due to being in the suburbs prior. After 1 week in our new home 13 year old rocky developed a terrible skin rash. He was up all hours of the night licking and crying, with red, pus filled bumps all over his belly. It broke my heart seeing him so miserable. I immediately tried Benadryl, which barley took the edge off. I changed his food. I took him to the vet. I was told it was probably just him reacting to the new environment. But nothing seemed to help Now 3 weeks later he is still miserable and I’ve tried everything! Until a few days ago I saw a little creature on his belly and realized he must have fleas! Apparently some dogs have terrible reactions to flea bites and NC weather is very flea friendly which I was unaware of. Well I ordered this medication praying it would work as I am not a bug person whatsoever and could barley sleep knowing they were in my house. Within 3 days It was at my door! Late last night I give them both their first treatment. Daisy is a treat snob, she sniffed it and then ate it without arguments. Rocky inhaled his as normal. I woke up this morning to dead fleas! Literally! Dead! Laying under both dogs as if they just dropped dead immediately, less than 8 hours after the treatment! It’s still the early stages, though my poor rocky has finally stopped itching and is currently sleeping away by my side peacefully for the first Time in weeks. I will watch very closely, though seeing the dead flea bodies laying there motionless, and my snuggly baby sleeping peacefully, my heart was given a huge relief and I will never miss a dose from here on out! Worth every penny for peace of mind

Well worth the money

I gave a pill to my dog and she wanted another, as if it were a treat. We played in the yard for a couple hours and I checked her for ticks before coming inside

I gave a pill to my dog and she wanted another, as if it were a treat. We played in the yard for a couple hours and I checked her for ticks before coming inside. She had a couple ticks on her but they were dead. She is only 11# and extremely hyper, so maybe that is why it worked so fast. But they definitely did the job!

Good product, but received almost expired meds

I purchased a box of Nexgard medication for my dog last June, as shown by the prescription label on the box in the picture. They said to use it by 06-2020 so I stored

I purchased a box of Nexgard medication for my dog last June, as shown by the prescription label on the box in the picture. They said to use it by 06-2020 so I stored it away, unopened, until spring time since I didn't need anymore medication last year (early winter). Went to grab it and noticed the box says it expired 10/2019. Little upset because not only did Chewy send me a 3 month supply of medication that would have only lasted from June - October, they also labeled it saying I could use it almost a year after it expired. This could have made my dog very ill. Normally I love Chewy, but this was a shocker to me! Typically all medications I order last for at least 2 seasons. The heartgard and revolution I ordered at the same time do not expire until 2021. Nexgard as a product is excellent -- have used it for years and never a flea, which is why I rated it a 5.

My pup loves being outside and playing in tall grass, so fleas are inevitable (esp in the summer). He had some skin irritation from constantly itching and biting, and every bath it seems no fleas would come out. Since taking this medicine, he’s stopped scratching and I don’t see any more fleas when I brush him. He’s a happy camper, and so am I!
