Do dogs hate lemon?
Not all dogs will be as adverse to citrus as they are to other smells, but the strong smell of lemons and oranges may be a natural, safe way to keep them away from unwanted areas.
It smells fresh and clean to humans.
You can fill a spray bottle with the juice as well.
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.
