Are fresh grapes good for dogs?
Grapes and raisins are known to be highly toxic to dogs, though research has yet to pinpoint exactly which substance in the fruit causes this reaction.
Unfortunately, grape/raisin toxicity can even be fatal.
Ingesting the fruit could potentially lead to acute (sudden) kidney failure in dogs.
Many believe it's instinctual behavior, harkening back to the days when your dog's wild ancestors would mask their scent to help them sneak up on their prey.
Wolves, for example, have been observed rolling in animal carcasses or the droppings of plant-eating animals, to cover up their own smell during the hunt.
Safe: Some Vegetables.
Your dog can have a healthy snack of carrot sticks, green beans, cucumber slices, or zucchini slices.
Even a plain baked potato is OK.
Don't let your dog eat any raw potatoes or any potato plants from your pantry or garden.
