Just wondering from those that have diabetic dogs (or if you're a vet/nurse who has been involved in the treatment of one), do you use human insulin? If so does it manage your dogs diabetes as well as canine insulin (if you have used both)? Is it more cost effective? Em's insulin dose just keeps going up at the moment, so her diabetes alone is costing me about $35 a week - not to mention the other medical issues!! I'm just wondering if people have used human insulin and does it work as well
