My bf just called me and told me his jack russel/beagle mix was shaking and panting heavily and she had been fine just a little earlier. Shylah is about 11 years old give or take, not exactly sure because she was a rescue. We don't have an emergency vet here, the reg vet isn't open until 10 am in the morning, my bf is very worried
Does anyone know what might have caused this?
