My pup has pravo...can anyone give me some serious home advice?

I,m sorry this is going to be tough on you. No animal should suffer like that . We also have recently experienced that with our black lab cross at 12 Weeks. Take him to the vet asap to get him rehydrate by iv. The syringe method helps pending if his keeping it down. 2 tsp should be ok but water is important also. About the food well I feel is also important but in small amounts. We also made a homemade electrolyte of tablespoon of honey, teaspoon of sea salt in one litre of water. Also administered by syringe in the mouth. So sorry its hard . Keep him hydrated. not sure about the blood in the pee, i just really suggest the vet asap.... only the vet can answer that one i think.......all the best to you..... ps there are lots of sites we saw on the web sites,
