I had read you could use this on pups. Well i goofed up and tried it. I almost killed 4 Blackcreek pups with it that are 9 weeks old. I took one to the Vet. and had fluids put through her and she is fine after 280.00 later. All the other pups were effected. She told me a pup less that 16 weeks have not got the membrane to the brain developed. My pups were nurelogic, they could not walk. They all lived through this but I learned an expensive lession.
