Do dogs hate citronella?
Many dogs just don't like the smell, period.
A spray to the nose might stop a dog that doesn't object to the smell, but not because of the smell - because of the spritz of liquid on his face.
Citronella is not proven to repel anything except mosquitoes.
Citronella oil is poisonous to pets, according to the ASPCA.
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.
