They have it at 1800petmeds.com. I think you can use Karo syrup in an emergency. An expert can tell you better than I. My breeder gave me Nutrical when I picked up Kalina at 12 weeks but I never had to use it. The very first sign is staring off into space. The symptoms get worse after that; falling over, seizures, total non-responsiveness at it's worse and that's when you need emergency treatment and IVs at the Vets. Good luck with your puppy.
