Yuko is a sweet and snuggly little 4 month old pup who is in desperate need of surgery to save his life . Yuko and his 3 siblings were only about 2 months old when they were found abandoned in the countryside of Peñuelas, a small coastal village in Puerto Rico. The tiny siblings were sleeping out in the open on a pile of rocks, near a cardboard box. At his foster home, Yuko was slow to put on weight. He struggled to keep up with his siblings. He developed a cough, and his foster mom noticed that his little heart was beating rapidly. When she snuggled with him, she could feel it pounding against his chest. The veterinarian took x-rays and found that Yuko had an enlarged heart. He was referred to a specialist, and was diagnosed with Patent Ductus Arteriosus (PDA), with evidence of heart failure. Yuko is very sick now, but he is an excellent candidate for surgery to repair his heart. With surgery, he should live a healthy life with a normal lifespan. Because he is such a cute and funny little guy, we know that he will be adopted quickly once he has recovered. Without surgery, Yuko probably won't live to be six months old. Please help us give him the chance to live the life he deserves.
