Best Dog Wormers of 2025

"I've had a great experience with this de-wormer. The pack comes with 6 chewables, making it a fantastic deal. It's incredibly effective! My dog's digestive issues were resolved quickly, and it's affordable and simple to use."

"I found this product to be really impressive! It was easy to give to my German shepherd puppy after noticing she had worms. Within 20 minutes, I could see the medicine was working, and the next day, there were no worms in her stool. No side effects except for some sleepiness!"

"I used this to help a neighbor's dog who was struggling with worms. After one dose, he started to gain weight and is much healthier now! This is a life-saver for him; he was really suffering before, and now he's doing great!"

"This product has been a great choice for deworming my dogs. I find it a bit pricey, but it definitely works. I give the pills directly, and within three hours, they may throw up a little, but that's normal."

"I really appreciate how helpful these pills have been for my dog. They came in handy and seemed to do the trick!"

"I've used this product for years and it consistently works. However, I wish there were coupons for loyal customers because I’ve spent so much. I found it’s actually cheaper at Petco and Petsmart than on Amazon."

"My pups came in contact with a dog that had worms. I decided to take extra precautions and gave this to them. Two weeks later, still no worms!"

"I found it easy to use, and it resolved my dog's issue in less than three days. He didn't get sick and had no trouble ingesting it."

"This is the exact medication my vet prescribed, but at a lower price. It worked as intended, and follow-up bloodwork showed negative results."

"This worked amazing on my dogs! They didn't need treats to eat it, and it helped clear any worms they might have had!"

"After rescuing a stray puppy, I used this product, and within 24 hours, it worked wonders! The outcome looked like a bowl of spaghetti. My puppy had no issues eating it mixed with wet food. I will use it again whenever needed!"

"Living in an apartment, I found a worm in my dog's stool and ordered this dewormer immediately. It arrived the next day, and after just one chewable, the problem was resolved in a couple of days! The only drawback was the size of the box for just one pill, but overall, this product worked fantastically."

"I was amazed that it worked in just 24 hours! Even my picky dogs took the tablets without any issues. This is a great product at a fantastic price!"

"I wasn't sure if it worked since my dogs didn't show any symptoms of worms, but I did feel I got value for my money. I wouldn't rate it five stars because nothing's perfect, but it was easy to use and I would buy it again."

"Es lo mejor, tengo 2 cachorros de 3 meses y funcionó rapidísimo. No les dio ningún efecto secundario. Lo volvería a comprar sin duda."

"I've raised about 8 litters of puppies in the past 5 years, and I use this solely for deworming. It works great, and my puppies don't mind the taste. It effectively eliminates and prevents worms, and the size is perfect for my 10 puppies per litter."

"This product worked perfectly for worming my dogs. I didn't have to deal with the mess of chalky pills."

"I breed Samoyeds and often face a dilemma with their worm issues. Taking them to the vet is a nightmare, especially with a whole litter. This product allows me to deworm them at home. While the instructions suggest starting at 2 weeks, I prefer to begin at 5-6 weeks for easier administration with food. The only drawback is the dosage instructions—they are based on 10 lbs and can be confusing. I usually give 0.5ml per lb, but I wish they had clearer instructions for smaller puppies."

"I've had dogs for over 50 years, and I've never seen a dewormer work as well as this one. It’s the only brand I trust for my dogs, and it works great for all sizes over 25 pounds."

"As someone who has cared for dogs for 45 years, I can confidently say this is the best wormer for the price. Great product!"

"I use this on all my rescue pups as soon as they arrive. They always test clean after using this. It's simple: just give one pill twice and you're done. Just remember to administer it again in two weeks to catch any immature parasites."

"My dogs absolutely love this product! There's no bad smell, so they think it's a special treat mixed in with their food. We've been using it since they were puppies, and it's highly recommended by their breeder. No worms ever found during vet check-ups!"

"Before using this wormer, I consulted with my vet. Everything went smoothly, and my dogs are doing great now!"

"I bought this based on a friend's suggestion, and the price was right. It seemed effective, but man, my dogs hated the taste! Administering it was a struggle with my six dogs, and I'll look for something easier next time."

"I had a wonderful rescue mix who was difficult to house train. After using this product, she passed quite an assortment of critters in her GI tract. It worked very well and her stools improved significantly, making things easier for both of us."

"My dog enjoyed the flavor and took the tabs without any fuss. I deworm my dog once a year as a precaution. No adverse effects were observed in my 11-year-old pup."

"I've used this product for all three of my dogs, and they consumed it without any issues. No gastrointestinal symptoms appeared in my dogs, who are of different breeds: Rottweiler, German Shepherd, and Aussiedoodle."

"I've used this dewormer for 7 years and it works great for my dogs!"

"After extensive research, I decided to use this instead of paying $250 for a vet treatment, and it worked perfectly!"

"When we brought our new puppy home, she was infested with fleas and worms. After using this product, she was full of energy and her coat became glossy. I'm planning to buy it again!"
