Rabies is a disease that can affect all warm-blooded animals. While the disease is most common in wild animals such as raccoons, foxes and skunks, the disease can be easily transmitted to your dog if it bitten by an infected animal. Most states currently require all pets to be vaccinated against the disease to prevent them from contracting it should they come in contact with an infected animal. If your dog has been bitten by a rabid animal it could take weeks or even months for the disease to show signs of the typically fatal infection. If you suspect your canine companion has come in contact with a rabid animal, there are a few symptoms you can look out for.
