my dog snoopy has recently had a hacking cough which i believe is kennel cough. I looked up dogs with kennel cough and he is making that exact same noise. My parents can not afford a vet so, i cant take him. He is also now vomiting little portions of white stuff, and he bites his paws a lot, no particular one but both vigorously. Can someone please help im scared he might die he is kinda acting tired,and staying under my bed all day, he used to be really energetic jumping everywhere
