Parvovirus can affect any dog that doesn't have immunity to parvo. Is your dog still acting normal? One of the first signs is a depressed appetite.
She ate her food last night, plus waffles the kids didn't finish and left on the table. The other day she ate some pork chops off the counter. I NEVER EVER feed cooked bones to my dogs, so of course I'm super concerned that it's from a bone splinter lodged somewhere.
