How Long Does Dewormer Take To Work?
As long as your dog has consumed all of the deworming medication, it should start to kill worms rapidly within two to six hours. After that time, you should see your dog begin to pass worms in his next bowel movement.
Best Dewormer For Puppies: Bayer Quad Dewormer Review
Bayer Quad Dewormer by Elanco Animal Health is a broad-spectrum chewable tablet effective against hookworms, roundworms, tapeworms, and whipworms. The active ingredients, praziquantel, pyrantel pamoate, and febantel, are the same as in Drontal Plus, a common vet-prescribed dewormer. But you don’t need a prescription for this product.
Bayer Quad is our pick for the best dewormer for puppies because it’s safe for dogs three weeks of age and older. Many other brands aren’t safe for puppies until they’re six weeks old or older. But it’s an excellent solution for dogs of all ages. It also only requires a single dose. You can give it as a chewable or break it up and sprinkle it onto your dog’s food. Many pet parents say it’s extremely effective; however, a few people report vomiting as a side effect.
