How 'bout this. Dog's love the taste of Insulin. I remember a few years back, my friends dog ate the carton that holds the insulin bottle and somehow got the rubber part out ot the top. It smelled bad to me, but the dog loved it. Just for clarification, I don't recommend insulin as a treat for the pups.
What happened to the dog? I got lucky, a few years ago I was switching my insulin cartridge and I left it sitting on the table while I went to the kitchen real quick. I was only out of the room for maybe 30 sec and my dog had it on the floor chewing on it. Thankfully she didn't puncture it but I freaked.
