If you do find that he is diabetic and needs insulin, I'd be happy to help out with syringes (even tho they aren't too expensive). I have leftover 1/2 cc syringes from when my RB dogs were on it, plus I use 1 cc syringes for myself for B-12 injections twice a month. I get them in boxes of 100 and I can just get doc to write me another prescription for them.
