sorry to hear about your dog wilgo tango, with hard dogs that take severe punishment its important to watch the colour of there urine, as this gives you an idea as to how and what the kidneys are filtering or how much stress there under from internal injuries, when the kidneys are under pressure feeding twice in a few hours is not the best thing to do, you did your best for your dog, keeping and working hard dogs is not easy, learning veterinary skills are a must for the after care involved, good hunting and best of luck with the rest of the season.
