Hi : ) How wonderful of you to support a K9 unit!! That's how i got started on anysoldier and I always have at least one
I have learned that a lot of the dogs are on restricted diets, and the handlers cant really feed them off diet. Some request you only send toys. My suggestion would be to write to the handler first and find out before you ship it. I can point you to a unit of 8 who will probably write back to you, just pm me if you need that.
Also, if you search, a lot of the units have picked up local "mascots" because there seem to be a lot of strays around. So if you can't find a working dog unit to support with dog food (who of course I'd love to see get the goodies first!!) then there is almost always a contact asking for food for their new friend :)
Hope that helps!! Shelly
ps The manufacturers website's almost always have the full ingredient lists for the dog foods...
