Thank you for your question. The dosage is based on the weight of the dog, and is given once unless reinfestation occurs.

Thank you for your inquiry. Before administering this product, we recommend obtaining a current and accurate weight for your dog. There are several ways to do this. On a regular home scale, weight yourself, then weigh yourself again while holding the pet. Subtract your weight from the combined weight of you and the dog. Or if you have a large dog, most veterinary clinics don’t mind if you drop in and weigh your pet. Either option should give you an accurate weight. The Quad Dewormer Tablets are made to work effectively within a range of weights, as listed on the product’s description. Although these types of wormers generally have a wide margin of safety, if you dose your dog with a size designated for a larger, heavier dog, we would recommend contacting your veterinarian. If your dog is several pounds above the weight range that you treated with, the dewormer may not work effectively.

Woodfam Thank you for your question. Steps should be taken to control fleas and rodents on the premises in order to prevent reinfection; otherwise, retreatment will be necessary. If reinfection occurs, tapeworm segments may be observed within one month of the initial treatment, which then you may re give the medication to your pet.
