Cool! I'm sure that a vet can write a 'scrip for them even if they don't keep them around the clinic. Good information. Thanks!
You are more than welcome.
By the way, the nitro comes in a tube and you have to put it on a piece of fabric, bandage, whatever, then bandage it up to keep it there. That's why you need to use gloves, it's easy to get it on yourself.
