I just got a puppy. Went to the pet store today to see if there was any dewormer available that is over the counter. I bought 10 mebendazole, 100 gm tablets for $14.99.
I didn't even know you could get mebendazole OTC. Surprising, for sure. 100 gm isn't the human dosage but in a pinch... Sergeant's Vetscription Worm-Away IV.
