We use Sentinel for our dogs as it starts working immediately.

I have been using this product for my pet for years and have not found any side effects

Kills three types of intestinal worms so that I do not have to purchase different treatments.

The product treats multiple parasites so that I do not have to spend on buying different products to treat different parasites.

I do not have to worry about my pet for a month as this product remains effective for an entire month to protect my pooch.
