Hi, my two year old shih-apso mix went swimming in a cold river about two days ago. Since then, he has been weak, has runny eyes, and is coughing up saliva. He has been getting plenty of rest and we even gave him some soup, however, nothing seems to be working. Just some added information, the day before he has gone swimming, he had been scratched by and outdoor cat. It drew a bit of blood, but that was it. Now we are a little confused and extremely worried as to what to do with or dog. Thanks in advanced!
