How many sultanas are toxic to dogs?
All grapes, raisins, currants and sultanas — as well as foods that contain them such as mince pies, hot cross buns, and fruit cake — can be poisonous to dogs, and potentially poisonous to cats.
It's thought the dried versions of the fruits are more likely to cause severe symptoms and potentially renal failure.
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.
