Signs are a dry hacking cough that causes us to gag. If a young puppy gets it the could get diarrhea, dehydrate and die. Some warning signs are lethargy, seizures, fever,diarrhea and watery eyes and nose. A bacterial disease that can be spread to other animals and also humans. It causes damage to our livers and kidneys.
Signs are muscle stiffness, fever, depression, vomiting, dehydration, blood clotting and anorexia.
In us puppies you can tell if we have it if we become suddenly lame and or have bad pain, swollen joints and we don't really want to move. Because it hurts so much animals get very depressed with this disease. I don't know that for sure though. But you can look at human web pages these pages are just for us puppies. With healthy older puppies like me, this is concidered a minor respiratory infection.
