HEY EVERYONE. I HAVE A QUESTION THAT IM HOPIN YALL CAN HELP WITH. I HAVE 2 6-MONTH BOXER PUPS-SAME LITTER. ONE IS JUST HUGE-ALREADY AND FILLED OUT WELL! HOWEVER, THE OTHER, WHO IS A WHITE BOXER WITH LOTS OF MARKINGS, IS NOT GAINING WEIGHT. 1ST VET SAID IT WAS HOOKWORMS, SO HE HAS BEEN TREATED 2X FOR THAT. THE HE SUGGESTED A SUPPLEMENT. I FOUND ONE CALLED DYNAMAX(UPCO) WHICH HAS 125 CALORIES PER TSP. HE ALSO GETS CANNED FOOD AND FRESH CHICKEN,PASTA. HE EATS REALLY WELL BUT STILL LOOKS EMANCIPATED. YOU CAN SEE HIS TAILBONE,SPINE, AND HIS BELLY IS JUST SUNK IN. CAN ANYONE OUT THERE OFFER SOME IDEAS? HE SEEMS SO WEAK AND PITIFUL. THANK YOU MY FELLOW BOXER LOVERS!
