Customers praise this monthly chewable for effectively preventing fleas, ticks, and heartworms with minimal side effects, with many reporting zero parasites and long-term safety over years of use. Most appreciate the convenience of a single oral dose compared to topical treatments, and many note their dogs willingly consume it as a treat. However, a notable group reports severe neurological reactions including seizures, particularly in puppies, raising safety concerns. Additionally, some customers experience frustrating ordering delays and prescription approval issues. Despite these drawbacks, most consider the product effective and convenient for parasite prevention.
