When a Feeding Concern Needs a Vet

The red flags around eating, appetite, and possible poisoning that mean call the clinic — some of them right now.

Most feeding questions are routine. But some signs around eating and digestion are the body's way of flagging a real problem, and a few are genuine emergencies where minutes matter — especially in a dog as small as a Yorkie, which has little reserve. This guide helps you tell the difference. It cannot diagnose anything; only a veterinarian who examines your dog can do that.

Appetite loss

A single skipped meal in an otherwise bright, playful adult may be nothing. But appetite loss that is sudden, complete, or paired with other symptoms is a reason to call. In puppies and very small Yorkies, a refusal to eat is urgent because of the risk of low blood sugar — don't adopt a wait-and-see approach with a tiny puppy.

Vomiting and diarrhea

  • One-off vomiting in a bright, otherwise-normal dog may resolve, but watch closely.
  • Repeated vomiting, or inability to keep water down, needs veterinary care — small dogs dehydrate quickly.
  • Severe, bloody, or persistent diarrhea warrants a call, especially with lethargy.
  • Vomiting or diarrhea plus weakness, a painful belly, or collapse is an emergency.

Weakness, wobbliness, and collapse

Weakness, trembling, disorientation, or collapse can accompany dangerously low blood sugar, dehydration, or a number of serious conditions. In a small dog these signs can escalate fast. Treat them as urgent and seek care rather than trying to manage at home.

Suspected poisoning

If your Yorkie may have eaten something toxic — chocolate, xylitol (birch sugar) found in sugar-free gum and many products, grapes or raisins, onions or garlic, macadamia nuts, or a medication or household chemical — act quickly. Because a Yorkie is small, even a modest amount of a toxin can matter.

Have this information ready when you call

  1. What your dog ate or what symptoms you're seeing, and when they started.
  2. Your dog's approximate weight — critical for a small breed.
  3. The product name or packaging if a toxin is involved (bring it with you).
  4. Any pre-existing conditions or medications.

When in doubt, call

You will never be criticized for calling a veterinarian about a small dog that seems unwell. This article is educational and deliberately avoids diagnosing — its whole purpose is to help you recognize when to hand off to a professional. If something feels wrong with your Yorkie, trust that instinct and get advice.

Frequently asked questions

When should I take my Yorkie to the vet for not eating?

Call if appetite loss is sudden or complete, lasts more than a day (much sooner for puppies and tiny dogs), or comes with vomiting, diarrhea, weakness, or lethargy.

What should I do if my Yorkie ate something toxic?

Act immediately. Contact your veterinarian or an animal poison control line, have your dog's weight and the product packaging ready, and follow their instructions — don't wait for symptoms to appear.

Is vomiting always an emergency?

Not always, but repeated vomiting, inability to keep water down, or vomiting with weakness, a painful belly, or collapse is urgent. Small dogs dehydrate quickly, so err on the side of calling.
