Hey, Sorry to hear about the pup, I used to be a vet-tech and now I'm a nurse, So I'll try and give you the best advice I can... Rat poison works similar to people's Coumadin (identical chemical, just super doses in the poision)... it thins the blood (the idea is to make the rat bleed to death). Avoid injury!!! Try to keep the puppy from bumping around anywhere. As far as attempts at treatment? Well, people that take coumadin are not allowed dark leafy green vegetables (spinach) because they cause the blood to become thicker (a natural source of Vitamin K) I'm not sure if the liquid broth off of spinach would help (relating to how much poision was consumed), but it would be worth a try. Try maybe boiling it down and concentrating it. There's no such thing as overdosing on Vitamin K. I'd be careful about other natural treatments, they can interact with other things and cause more problems than you want.
