Should I give my puppy Bendex dewormer? What's the safe dose?

This is a medication that is not commonly used in the U.S. Also unfortuantely since none of the experts on this site have physically examined Pinky 2, we cannot legally give you the dosage for this dewormer. The best option here is to contact your local vet who has already examined Pinky to give you the dosage for this drug. This drug also have a higher potential for toxicity in pets, so I would even consider giving a different dewormer that is safer for dogs, depending on what worm you are treating for.
I hope that Pinky gets rid of his parasites soon! Best of luck moving forward and take care.
