If you have to give some oral meds to your horse, this is the way to go.

It would be even cooler if your dog could operate it!

Works just like it says. I use it every time I change my fish's water and they seem to do fine.

Cleans the tank like a filter says it should and it's not loud.

Looks silly, but sometimes you just have to use them if your pet won't quit chewing stiches.
