Yorkshire Terriers, affectionately known as Yorkies, are charming, spirited companions. However, their small size and often sensitive digestive systems mean that owners must be particularly vigilant about their diet. Feeding your Yorkie the wrong foods, even in small amounts, can lead to serious health issues, ranging from upset stomachs to life-threatening poisoning. As a devoted “pawrent” on Dog Care Story, understanding what foods to avoid is crucial for ensuring your beloved Yorkie lives a long, healthy, and happy life. This guide will walk you through a comprehensive list of foods that pose a risk to your Yorkie, helping you make informed decisions to protect their well-being.
Yorkies, being a “toy breed,” are predisposed to certain gastrointestinal sensitivities and conditions like pancreatitis. While their adorable, begging faces can be hard to resist during meal times, it’s vital to prioritize their health over momentary indulgence. Many human foods are pawfectly safe for dogs, some are only safe in moderation, and a significant number are entirely off-limits due to their toxic effects. Ensuring your Yorkie receives appropriate nutrition and avoids harmful substances is a cornerstone of responsible pet ownership.
Foods Yorkies Should Absolutely Avoid (The Big NOs)
Some foods are highly toxic to dogs, and even a tiny amount can cause severe harm or be fatal, especially for a small breed like a Yorkie. These items should be kept completely out of reach.
1. Sugar-Free Gum and Candies (Xylitol)
Sugar-free products, particularly gum and candies, often contain xylitol, an artificial sweetener that is lethally toxic to dogs. Ingesting even small quantities of xylitol can cause a rapid and significant release of insulin in your Yorkie’s body, leading to hypoglycemia ( dangerously low blood sugar), seizures, liver failure, and potentially death. Given a Yorkie’s small stature, the impact of xylitol is even more profound, with symptoms appearing within hours. Always check ingredient labels for xylitol in human foods, medications, and even some peanut butters. Keeping all forms of gum and sugar-free candies securely stored and out of paw’s reach is paramount for your Yorkie’s safety.
2. Avocado
Avocado, a healthy fat source for humans, is a strict no-go for Yorkies and all dogs. The primary culprit is persin, a fungicidal toxin found in the leaves, pit, bark, and fruit pulp of the avocado plant. Persin can cause a range of adverse effects in dogs, including vomiting and diarrhea. More severely, it may lead to fluid accumulation in your Yorkie’s lungs and chest, potentially resulting in respiratory distress, heart problems, and pancreas issues. Furthermore, the large avocado pit presents a significant choking hazard and can cause dangerous intestinal blockages if ingested by a small dog.

3. Grapes & Raisins
Despite their delicious taste for humans, grapes and raisins are highly toxic to dogs. The specific toxic substance remains unknown, but what is certain is their detrimental effect on canine health. Even a single grape or raisin can make a Yorkie sick, with the risk escalating with consumption quantity and the dog’s smaller size. In severe cases, grape and raisin ingestion can lead to acute kidney failure within 72 hours. This is a critical warning for all dog owners: keep these fruits strictly away from your pets.
4. Chocolate
Chocolate is a well-known canine toxin, primarily due to its content of theobromine and caffeine. Both are stimulants that dogs metabolize much more slowly than humans, leading to their accumulation in the system to toxic levels. The darker and more bitter the chocolate, the higher the concentration of these harmful compounds, making it more dangerous for your Yorkie. Symptoms of chocolate poisoning can appear within 6 to 12 hours and include vomiting, diarrhea, restlessness, increased heart rate, and, in more severe cases, seizures, tremors, heart failure, and collapse. Beyond the specific toxins, chocolate is also high in fat and sugar, which can independently cause gastrointestinal upset or pancreatitis.

5. Taro
Taro, often enjoyed in various culinary forms by humans, is unfortunately toxic to Yorkies. Whether raw or cooked, taro contains calcium oxalate crystals that can cause poisoning. Ingestion typically leads to severe oral irritation, including burning sensations in the mouth, tongue, and lips, excessive drooling, and gastrointestinal issues like vomiting and diarrhea. In extreme cases, taro consumption can even result in kidney failure in dogs. Both the root and the plant pose the same danger, so it’s essential to keep taro products away from your Yorkie.
6. Spicy Food
While the aroma of spicy foods might be appealing, they are incredibly detrimental to a Yorkie’s delicate digestive system. Ingredients like chili peppers and hot sauces contain capsaicin, which can cause significant irritation and upset. Unlike humans who can consciously choose to eat spicy foods, dogs rely on their owners to provide safe options. For Yorkies and other dogs, spicy foods can lead to diarrhea, constipation, excessive gas, abdominal pain, and vomiting. These symptoms highlight that spicy foods are truly toxic to dogs, capable of causing more than just temporary discomfort. Therefore, any food seasoned with significant spices should be completely off-limits.

7. Unripe Tomatoes
The ripeness of a tomato significantly impacts its safety for Yorkies. Unripe (green) tomatoes and tomato plants contain solanine, a substance that is dangerous to dogs. Solanine is concentrated in the green parts of the plant, including stems and leaves. If you have tomato plants, ensure they are in an area inaccessible to your Yorkie to prevent accidental ingestion. While ripe tomatoes have a much lower solanine content and might be tolerated in very small, occasional amounts, many owners choose to avoid them entirely to err on the side of caution due to their acidity and the potential for residual tomatine.
8. Alcohol
Under no circumstances should alcohol be given to your Yorkie. Alcohol and dogs simply do not mix. Even a small amount of an alcoholic beverage can be highly toxic, leading to severe adverse conditions. Dogs are much more sensitive to the effects of alcohol than humans. Ingestion can cause significant drops in blood sugar, blood pressure, and body temperature. Symptoms include vomiting, disorientation, incoordination, tremors, respiratory depression, and potentially coma or death. Your Yorkie’s happiness can be found in safe treats, toys, and your undivided attention, not in a sip of your drink.

9. Certain Nuts (Macadamias, Walnuts, Hickory)
While some nuts, like peanuts (in moderation and unsalted), are generally safe for dogs, others are dangerous. Macadamia nuts are particularly toxic to dogs, causing symptoms such as weakness, vomiting, tremors, and difficulty walking. Walnuts, though not as acutely toxic as macadamias, can still cause significant health problems. Their high-fat content can trigger pancreatitis and gastrointestinal upset, and their size can pose a choking risk or lead to bowel obstruction in small dogs. Similarly, hickory nuts can cause an upset stomach and bowel obstruction. It is important to know which fruits can dogs have and not have as part of a balanced and safe diet.
10. Garlic
Garlic, a powerful ingredient for humans, must be excluded from your Yorkie’s diet. While very small, infrequent doses might not cause immediate major side effects beyond some gas, garlic is considered toxic. It belongs to the Allium family, like onions, and contains compounds called disulfides and thiosulphates. These compounds can cause oxidative damage to a dog’s red blood cells, leading to various forms of anemia, including Heinz body anemia and hemolytic anemia. Symptoms of garlic poisoning, which may be delayed, include rapid breathing, dark-colored urine, lethargy, vomiting, diarrhea, and a lack of appetite. Always be vigilant for these signs if you suspect your Yorkie has ingested garlic. For more information on harmful ingredients, you might want to learn about what meat is harmful to dogs.
Foods to Feed in Occasional, Small Quantities (If at All)
Some human foods aren’t outright toxic but can cause problems for Yorkies due to their sensitive digestion or specific components if consumed in large amounts. It’s often safer to avoid these entirely or offer only the tiniest, rare lick.
11. Lemons & Limes (Citrus Fruits)
The refreshing citrus flavor of lemons and limes might appeal to humans, but the high concentration of citric acid can be harmful to Yorkies. Dogs generally do not enjoy the bitter and sour taste of citrus anyway. While a few licks might not cause immediate harm, consuming too much citric acid can lead to significant gastrointestinal upset, including diarrhea and vomiting. Limes, which are even higher in citric acid, are particularly concerning, with the leaves, peel, or fruit itself capable of making your Yorkie sick. It’s generally best to keep all citrus juices, lemonades, and grapefruits away from your pet.
12. Onions
There is no safe part of an onion for dogs. All parts—leaves, juice, stem, root, and core—are toxic, whether cooked or raw. Onions contain the same harmful compounds as garlic (disulfides and thiosulphates) that can lead to anemia in dogs. Symptoms of onion toxicity include a lack of energy, loss of appetite, pale gums, and even red urine. While a larger dog might tolerate a small amount without immediate severe symptoms, Yorkies are highly susceptible, and owners should never take chances. For those curious about safe food options, explore what is good food for dogs to eat.

13. Milk & Dairy Products
While not entirely off-limits, dairy products like cow’s milk should only be given to Yorkies in very small, infrequent amounts. Many dogs, similar to humans, are lactose intolerant, meaning they lack the enzyme lactase needed to digest lactose, the sugar in milk. Consuming dairy can lead to bloating, loose stools, an upset stomach, diarrhea, and vomiting. While a tiny piece of cheese here and there might be okay for some Yorkies, regular intake of milk and other dairy products should be avoided to prevent digestive discomfort. For young dogs, understanding what does a month old puppy eat is vital to ensure they get the right nutrition.
14. Ripe Tomatoes
As mentioned, ripe tomatoes contain significantly less solanine than unripe ones and are not considered poisonous in the same way. A very small slice of a ripe cherry tomato might be tolerable as an occasional treat for some Yorkies, ensuring it’s sliced to prevent choking. However, due to their acidity and the potential for residual tomatine, even ripe tomatoes can upset a Yorkie’s sensitive stomach if given in large quantities. Many owners opt to avoid them entirely to eliminate any risk.
15. Coconut (in moderation)
Coconut flesh and oil are generally non-toxic for dogs and offer some health benefits due to their anti-inflammatory properties and antioxidants, which support skin, joint, and immune health. However, coconut also contains medium-chain triglycerides, which can cause gastrointestinal upset, including diarrhea, if consumed in excessive amounts. Therefore, while not strictly “bad,” coconut should be offered in very small, controlled quantities to avoid digestive issues in your Yorkie.
16. Coffee & Tea (Caffeine)
Caffeine, found in coffee, tea, soda, and energy drinks, is a stimulant that can be harmful to dogs. Ingestion can lead to hyperactivity, restlessness, hypertension, an elevated heart rate, tremors, and in severe cases, seizures and collapse. While a tiny lick of your coffee or tea might not cause significant caffeine poisoning, the main concern lies with coffee beans and tea bags, which contain concentrated amounts of caffeine and are considered toxic to dogs. Keep these items well out of reach.
17. Oranges, Tangerines, & Mandarins
These citrus fruits offer some beneficial nutrients like Vitamin C, potassium, and fiber. However, due to their sugar content and acidity, Yorkies should only consume them in very small amounts, if at all. Many dogs aren’t particularly fond of citrus flavors anyway. If your Yorkie does enjoy them, a small, peeled slice as a very infrequent treat might be acceptable. Always remove the peel, as its thickness and essential oils can cause digestive discomfort. It is also important to consider what vegetables can american bullies eat for comparison on safe vegetable options.

18. Raw Eggs
Feeding raw eggs to your Yorkie carries risks similar to humans, primarily the possibility of salmonella contamination. While dogs historically consumed raw eggs in the wild, domesticated pets have different immune systems and are susceptible to foodborne bacteria. As a precaution, it’s safer to cook eggs thoroughly before serving them to your Yorkie, which destroys any potentially contaminating bacteria. Cooked eggs can be a good source of protein, B vitamins, and iron for dogs.
19. Salty Foods
Excessive salt intake can be very dangerous for Yorkies. Just as it can dehydrate humans, too much salt can cause significant thirst, frequent urination, and lead to sodium ion poisoning in dogs. Symptoms include vomiting, diarrhea, tremors, seizures, and in extreme cases, it can be fatal. Therefore, processed foods high in salt, such as lunch meats, cured meats (like ham), salted snacks, and heavily seasoned human meals, should be completely avoided in your Yorkie’s diet. Always ensure your Yorkie has access to fresh, clean water to prevent dehydration.
20. Greasy & Fatty Foods
Yorkies are particularly prone to pancreatitis, a serious and painful inflammation of the pancreas, which can be triggered by consuming high-fat foods. Deep-fried foods, fatty table scraps, and rich gravies should never be part of your Yorkie’s diet. When a Yorkie ingests too much fatty food, the pancreas gland can become inflamed, releasing digestive enzymes inappropriately and causing severe abdominal pain. Symptoms of pancreatitis include panting, weakness, diarrhea, vomiting, and fatigue. This condition often requires emergency veterinary care and can be life-threatening. Be especially cautious during holidays or family gatherings when tempting high-fat foods are often present.

What If Your Yorkie Eats One of These Foods?
Despite your best efforts, accidents can happen. If you suspect your Yorkie has ingested a harmful food, immediate action is crucial.
First, stay calm and observe your Yorkie closely for any abnormal reactions or behavioral changes. Symptoms like vomiting, diarrhea, lethargy, tremors, seizures, or difficulty breathing warrant immediate veterinary attention. Do not wait to see if the symptoms improve; acting fast can significantly improve your Yorkie’s prognosis.
If you believe the ingestion involves a known poison, your veterinarian may refer you to a specialized pet poison control center. For instance, the ASPCA Animal Poison Control Hotline is available 24/7 at (888) 426-4435, though a consultation fee typically applies. Provide them with as much information as possible: what your Yorkie ate, how much, and when.
In cases of mild stomach upset, your veterinarian might recommend a bland diet, such as boiled white rice mixed with plain, shredded chicken. Cook the rice until it’s very soft and watery, like a porridge, to help soothe their sensitive tummy. Encourage your Yorkie to drink plenty of water to stay hydrated. Often, your Yorkie may just need to pass the offending food. However, always consult a veterinarian to determine the best course of action.
Knowing “What Not To Feed A Yorkie” is paramount to their health and longevity. By being diligent and informed, you can prevent many common and severe health issues, ensuring your furry friend remains a happy, energetic part of your family. Keep this list handy and always prioritize your Yorkie’s well-being above all else.
