Questions & Answers

21 Customer Questions

Do they have this for small dogs? Like 5lb-15lb?

Do they take this every month?

Answer by Chewy • Feb 20, 2023
One dose of the de-wormer is your dog’s recommended monthly treatment. If you need to retreat your dog, we recommend consulting with your veterinarian and have them perform a fecal test on your dog, to rule out any other issues.

Does this work for whipworms

Answer by Chewy • Mar 02, 2022
This treatment treats and controls 2 types of tapeworms, 2 types of roundworms and 3 types of hookworms.

Should the dosage be administered monthly as a preventative or is it only to be administered if worms are present?

Answer by Chewy • Oct 03, 2023
This requires treatment only once and as needed. Re-treatment of your dog may be necessary as determined by laboratory fecal examination and/or if your dog is living where re-infections are likely to occur. Consult your veterinarian for assistance in the diagnosis and prevention of re-infection. In case of re-infection with tapeworms, consult your veterinarian for advice on how to remove fleas from the dog and the environment.

I do have to say if you have a very picky dog like my English springer spaniel you will probably have a little bit of a hard getting her to take the pill. She’ll take next guard no problem, but she spit this out multiple times and I had to do a dance to try to get her to take the pill.

We have four dogs, a fenced in acre in our backyard and a dog door. A recipe for disaster. When we found the rabbit head on our living room floor we knew we had tapeworms to deal with. Not knowing if one or all four had a taste of raw food, I opted to deworm all the dogs. I chatted with a Chewy representative on line and she helped me to find these meds for our dogs. I waited three weeks from the rabbit murder to give the deworming treatment which was last weekend. So far the dogs seem fine and we are hoping to see dead tapeworms soon.

Lightning fast shipping!

Very please with the speed of processing and shipping. Glad the meds were only precautionary and not really necessary. Safety first and always for my boy!

This was easy to order and easy to give to our dog. I am not sure how fast it worked as he runs to the woods and hides to go to the bathroom! But he doesn’t have an itchy butt any more so I feel it worked pretty well!

This product works as long as you use it on a regular basis I was buying the one for smaller dogs because my dog is right on the weight limit but I was having to give him 2 of those at a time it was really expensive so I started buying these one's I just cut one in half and give him that it's cheaper and technically I get 4 doses out of 2 pills where I was paying double for a box of the others that only gave me 3 doses so just see what your dog weighs and how many milligrams to give them, I highly recommend this product it's one of the more affordable options for someone on a budget and it works, also my dog has never had any side effects or reactions to this medication

How to get rid of Tape Worms.

I used the powder packages day 1, then a Nexguard chewable day 2, then this 7 way Dewormer day 3. I haven't seen a worm since. And the dogs act better too now.
