Foods Dogs MUST Avoid

  • Chocolate which can cause seizures in dogs.
  • Coffee and tea can cause similar problems as chocolate.
  • Raisins and grapes can cause kidney failure.
  • Nutmeg can also cause seizures.
  • Raw eggs could contain salmonella, so they’re not worth the risk.
  • Onions are not advised as they can interfere with blood circulation.
  • Macadamia nuts can cause dogs to have tremors and lead to paralysis.
  • Other food cautions include moldy foods, yeast dough and fruit pits. Many fruit pits contain cyanide.
  • Xylitol – found in sugarless gum and candy, symptoms mimic hypoglycemia. Deadly.
