My 9 y/o Dalmatian has recently stopped eating her food. She drinks a lot of water. She has been eating cat droppings from a litter box and I recently gave her a dewormer. Could she have an upset stomach from the cat's poop and litter or is there something more wrong?

It is okay for your dog to go off their food, as long as it is no more than three days, my dog does this occasionally. You can take is normal dry food, and give it as treats, asking him to sit and paw and so on. As for the eating of the feces it could possibly upset you dogs stomach. With our dog we had to turn the litter box around so she could not fit her head in the box. If your dog stays off the food for more than three day then contact your veterinarian. Please keep in mind that I am not a vet and this is only a suggestion, I would like to leave you with PetEducation.com. It is a wonderful site filled with information. I hope that I was in some way helpful to you. (O:
