Liquid Dog & Cat Dewormer – Roundworm Support for Puppies and Kittens

Support your pet’s wellness routine with this Liquid Dog & Cat Dewormer, formulated to help manage roundworms in puppies and kittens. Made with piperazine citrate, this liquid wormer is designed for easy administration and can be mixed directly into food or water for convenient use.

Suitable for dogs and cats 6 weeks of age or older, this multi-species formula is intended for routine parasite management as part of responsible pet care. Always follow package directions carefully and consult your veterinarian with any questions regarding parasite prevention or treatment.

Key Benefits

  • Roundworm Support: Formulated with piperazine citrate to help address roundworms.
  • Easy Liquid Administration: Mix into food or water for simple dosing.
  • Multi-Pet Use: Suitable for dogs and cats, including puppies and kittens 6 weeks and older.
  • All Breed Friendly: Designed for small, medium, and large dogs, as well as cats.
  • Made in the USA: Produced to support quality and consistency.
  • Generous Size: 12 oz bottle supports multiple treatments as directed.

How It Works

Piperazine citrate works by paralyzing susceptible roundworms so they can be naturally expelled from the body through normal digestive processes. This product is intended for roundworm support only and does not treat all types of parasites.

Usage Guidance

Administer only as directed on the package label. Dosage varies based on pet weight and species. For best results and ongoing parasite management, consult your veterinarian.
