These are generic Benedryl and work great! They are cheap and work great for allergies!
The tablets work the best for my dogs, they can't take the capsules because they can't swallow them. The tablets are also easily broken into two pieces if you have a really small dog.
My dog has allergies really bad in spring and Summer and this has worked great for him. I can't tell that it makes him drowsy or any other negative side effect.
