My Yorkie Is Not Eating: Appetite Loss Causes and What to Do

When a Yorkie stops eating or eats much less, it’s worrying. The cause can be medical, behavioral, or related to food or routine. This guide helps you understand common reasons for appetite loss, when to see the vet, and what you can try at home (e.g. better food, routine, and environment).

Quick Answer

If your Yorkie isn’t eating, first rule out medical causes: dental pain, stomach upset, infection, or other illness. See the vet soon if they skip meals for more than 24 hours, act lethargic, vomit, have diarrhea, or lose weight. Common non-medical reasons: picky eating, too many treats or table scraps, sudden food change, stress, or an uncomfortable eating spot. Fix what you can (consistent meals, good quality food, quiet place to eat) and get a vet check when in doubt.

Common Causes of Appetite Loss

Cause	What to do
Dental pain	Check mouth for broken teeth, redness, or tartar. See vet for dental care.
Upset stomach / illness	One skipped meal can be normal; 24+ hours without eating or any vomiting/diarrhea/lethargy → vet.
Picky eating	Set meal times; offer high-quality food; avoid rewarding refusal with treats or people food.
Too many treats	Keep treats under ~10% of daily calories so they’re hungry at mealtime.
Sudden food change	Transition over 7–10 days when switching foods.
Stress	New home, new pet, or separation anxiety can reduce appetite. Reduce stress and keep routine.
Environment	Feed in a quiet, safe place; clean bowls; avoid competition with other pets.

When to See the Vet

Schedule a vet visit if your Yorkie:

• Has not eaten for 24 hours or more (or less in a very small or young dog).
• Is vomiting, has diarrhea, or seems lethargic or weak.
• Is losing weight or drinking much more or less than usual.
• Shows pain (e.g. around the mouth, belly, or when moving).
• Has other new symptoms (coughing, limping, hiding, etc.).

Small dogs like Yorkies can become weak or hypoglycemic if they don’t eat; don’t wait too long to get a checkup.

Medical Conditions That Can Reduce Appetite

Dental disease, gastrointestinal issues, infections, organ disease, pain, or certain medications can all cause appetite loss. Your vet will examine your dog and may suggest bloodwork, imaging, or dental care. Treating the underlying condition usually helps eating improve.

The Picky Eater Problem

Yorkies are known for being fussy. If the vet finds no illness, try:

• Scheduled meals: Offer food for 15–20 minutes, then remove it. No all-day grazing.
• No table scraps or extra treats when they refuse a meal—that rewards not eating.
• One good small-breed food; avoid constant switching.
• Quiet feeding spot away from noise and other animals.
• Slightly warmed or room-temperature food (not hot) if they prefer it.

If they still won’t eat, the vet can rule out hidden medical causes and suggest a diet or appetite stimulant if needed.

Human Food and Your Yorkie’s Diet

Feeding human food can make Yorkies hold out for “better” food and refuse kibble. Some human foods are also toxic (e.g. chocolate, xylitol, grapes, onions). Keep people food to a minimum and use dog-safe treats in small amounts so they stay hungry for their main meals.

Encouraging Healthy Eating Habits

• Same time, same place each day.
• Transition slowly when changing food (mix old and new over 7–10 days).
• Clean bowls and fresh water.
• No stress at mealtime—no yelling, other dogs stealing food, or crowding.

If your Yorkie is stressed when alone, address that separately; it can improve appetite too.

Summary: What to Do When Your Yorkie Won’t Eat

1. Rule out illness—vet check if they skip meals, seem unwell, or lose weight.
2. Check mouth—dental pain is a common cause; see dental care.
3. Stick to a routine—set meals, limit treats, no table scraps.
4. Offer good food suited to small breeds; transition slowly if you switch.
5. Reduce stress and feed in a calm place.
