Panacur contains fenbendazole, an antiparasitic medication used in veterinary medicine. The medication treats certain animal parasites, and the dose depends on species, weight, age, health, and product.
Because different Panacur formulations can have different concentrations and approved uses, pet owners should always check the product label and follow their veterinarian’s instructions. Do not assume that a Panacur dose intended for dogs is appropriate for cats, kittens, or other animals. Panacur puppies dosage should be based on the puppy’s weight and treatment needs.
Panacur dosage for dogs depends on the dog’s weight and the condition being treated. Fenbendazole for cats dosage chart by weight shows dosing guidance based on body weight. This guide explains commonly referenced Panacur dosing information and provides easy-to-read charts for dogs, puppies, cats, and kittens.
Panacur for Dogs and Puppies
For dogs, the FDA-approved labeling for Panacur C lists a fenbendazole dose of 50 mg/kg (22.7 mg/lb) once daily for three consecutive days. Panacur C is labeled for adult dogs and puppies 6 weeks of age or older for certain roundworms, hookworms, whipworms, and tapeworms.

Calculated from the labeled 50 mg/kg dose. Actual administration should follow the specific product’s packet or measuring instructions rather than this calculated table. Panacur dose for kittens should be given according to veterinary instructions. Check the fenbendazole dose for calf per kg before treatment.
The Panacur C label matches packet sizes to the dog’s weight and may recommend the next higher packet for dogs between weight ranges. Mix the medication with a small amount of the dog’s food, and make sure the dog eats it all.
Panacur Dosing for Puppies
Puppies can be especially susceptible to intestinal parasites. Panacur C is labeled for puppies 6 weeks of age and older. The labeled canine regimen is 50 mg/kg daily for three consecutive days.

Veterinarians should check puppies younger than the labeled age, underweight puppies, or sick puppies before treatment. Young animals may need different parasite control based on the parasite they have.
Fenbendazole also treats parasites in cats, but don’t copy the canine Panacur C dose for cats. The FDA-approved Panacur 22.2% granule documentation includes certain Felidae species and lists a different regimen for those labeled species: 10 mg/kg once daily for three days. Panacur for cats dosage varies depending on the cat’s weight and parasite infection. Liquid Panacur dosage for dogs should be measured carefully using the recommended dose.
Panacur dosing for cats should follow veterinary guidance based on weight and health needs. This distinction is important because Panacur products and their approved indications can vary by species and formulation. Panacur liquid dose for dogs varies based on weight and treatment requirements.

This is a mathematical reference based on the 10 mg/kg regimen appearing in the FDA documentation for certain Felidae. It is not a universal dosing recommendation for domestic cats. A veterinarian should determine the appropriate dose and formulation for an individual cat or kitten. Panacur dose for cats depends on their body weight.
What Parasites Does Panacur Treat?
For dogs, the FDA-approved Panacur C label includes treatment and control of certain roundworms, hookworms, whipworms, and tapeworms. The exact parasite matters because not every intestinal or respiratory parasite responds to the same treatment plan. A veterinarian may recommend fecal testing or other diagnostic testing before selecting a dewormer. Dosage for Panacur liquid for dogs should be confirmed with a veterinarian before use.
It is also important not to extend treatment simply because a pet still has symptoms. FDA has reported cases of bone marrow hypoplasia and pancytopenia in dogs associated with extra-label fenbendazole use, particularly when treatment continued beyond the labeled three-day duration. Panacur liquid dosage for dogs is calculated according to the dog’s weight. Panacur liquid for dogs dosage should follow the product label or veterinary advice.
How to Give Panacur
Panacur comes in granules and other formulations. For Panacur C granules, the FDA label instructs owners to mix the medication with a small amount of the animal’s usual food and make sure the dog consumes the entire medicated portion. Panacur for kittens dosage depends on their weight and age. Always:
- Weigh your pet accurately before dosing.
- Check the concentration on the package.
- Follow the instructions for that specific formulation.
- Complete the prescribed treatment.
- Avoid combining dewormers unless your veterinarian recommends it.
- Contact a veterinarian if vomiting, severe diarrhea, weakness, or other concerning symptoms occur.
Can You Use a Dog Panacur Dose for a Cat?
No. Species-specific dosing is important. Panacur Dosing Charts provide simple weight-based dosing guidance. A dose that is appropriate for a dog may not be appropriate for a cat. Even within the same brand, products can have different concentrations, labels, and approved species. Panacur fenbendazole cats dosage should be based on the cat’s weight and veterinary advice. Panacur dosing for puppies depends on puppy weight and veterinary recommendations.
The FDA currently recognizes fenbendazole products for veterinary use in dogs and cats, including circumstances where veterinarians may use products in an extra-label manner when appropriate. Refer to Panacur Dosing Charts for deworming dose guidance.
Final Thoughts
Panacur can effectively treat parasites when you use the correct dose and duration for the animal. For dogs and puppies covered by the Panacur C label, the standard labeled regimen is 50 mg/kg daily for three days, while feline dosing requires more careful attention to the specific product and veterinary direction. Panacur dosing for puppies depends on puppy weight and veterinary recommendations. Panacur dosage calculator can help estimate doses based on body weight, but veterinary guidance is important.
The charts above are useful for understanding weight-based dosing, but they should not replace professional veterinary advice. Panacur Dosing Charts make dose information easy to follow. Always verify the exact Panacur formulation, concentration, species, age, and treatment indication before administering the medication.
