If your pet is otherwise healthy and is still drinking plenty of water, though, they can go three to five days without a morsel of food and still be relatively alright.
They’re Fussy Eaters
Yup, sometimes your pooch is just being a prima donna. They might develop a taste for steak and turn their nose up at chicken, or vice versa.
They Have an Allergy
It’s possible your pet is simply allergic to something that dominates its diet, causing them to feel ill.
Your furry friend can also get the blues, and lose interest in their food as a result. Usually, they’ll also become less playful and active if this is the case, and their sleep schedule will change.
