There are a few drawbacks to consider. Side effects can occur, although they are generally mild, so it’s important for pet owners to monitor their dogs after treatment for any unusual reactions. Additionally, some pet owners may find the need for multiple doses depending on the severity of the infestation, which could be inconvenient. From a veterinary perspective, Elanco is a trusted brand, but it’s always advisable to consult your veterinarian before starting any deworming regimen.
