The Pit Bull is really not a separate breed but one of several, or even a combination of two or more. Because they have been used and abused as fighting animals, some communities have banned them. But people who really know these dogs will tell you what wonderful pets they can be.
If you have had the flu, you know how bad you feel. You also know it can easily turn into something more serious (such as pneumonia) if you don't take care of yourself. Canine influenza can be just as dangerous for your dog - maybe even more so because your pet probably has no natural immunity to it!
