Rottie Pup getting bonier and weaker but skin still loose enough not to be dehydrated, very hungry and thirsty, eats greedily, vomits easily, coughs when drinking water, rests a lot, when picked up, throws head back and remains very limp, does come when called, does eat and drink, does try to play, fluid in mouth sounds "tacky" like a dry mouth, and swallows a lot, seems to be getting cold, especially head shaking when he keeps it up, and rest of pups fine. Was inoculated 2 weeks ago and dewormed. Unsteady weak gait, still inquisitive. Mother very rough with pups, is it an injury or illness? How can I help until Saturday when I can go to Vet? Did have a runny tummy and serious vomiting 3 weeks ago, but it seemed to clear up. Can feel a knob by breast bone. Please help...

If it were my pup, I would take it to the vet right away. Either your regular vet or the emergency vet. At least call the vets office for advice.

Please get this dog to a vet.

If you need a third voice to chime in, I will. I agree with both posters above. Annie, please do not wait until Saturday. That puppy needs a vets attention ASAP. We cannot examine him online and anything we tell you would just be a guess. You need an answer and a proper course of treatment immediately.
