No, Desdemona, you were right to go to the vet. By the time you weeded out all the possibilities, your dog might have got in very bad shape.

I agree with those who recommend premium food. I feed my cats Science Diet or Eukanuba foods. It costs more per pound, but less of it is needed to satisfy them Also, their boxes are far less stinky because supermarket cat food contains cheap, irritating ingredients which cause something like low-grade diahrrea.
