Yorkshire Terriers are small, active dogs that love to eat. This means that they will try to eat anything they can get their paws on. Therefore, you should know what not to feed a Yorkshire Terrier to avoid serious health problems.

What Not to Feed a Yorkshire Terrier

Many pet owners give their dogs table scraps and people food which can be harmful to your pet. You should always stick to feeding them their food and treats that were made specifically for dogs.

There are several foods to avoid for Yorkies, including:

  • Grapes
  • Raisins
  • Onions
  • Garlic

You also want to avoid drinks like coffee or tea as these contain caffeine which is toxic for dogs. Your Yorkie may also have a problem with eating other animals’ food or canine treats. Here are some things you should never feed your terrier:


Chocolate contains theobromine and caffeine, which is poisonous when ingested by Yorkies. It causes vomiting, diarrhea, and even seizures in some cases. Ensure that you store all types of chocolate somewhere your dog cannot reach it if you want to avoid a potential emergency.

The darker the chocolate, the more hazardous it is to your Yorkie because it includes even more of these chemical substances. Smaller dogs can be affected by a smaller quantity of chocolate than bigger dogs.

Grapes and Raisins

Grapes and raisins are hazardous to Yorkies, resulting in severe damage, such as acute kidney failure. Keep grape and fruit salads off your dog’s menu. Just one of these fruits can induce an extremely negative response.

If you suspect that your dog has consumed even a small amount of grapes or raisins, immediately take them to the veterinarian.

Nuts and Seeds

Some types of macadamia nuts are also harmful to dogs. A terrier may only get sick if they eat too many macadamia nuts at once. However, some Yorkies can develop toxicity in the nervous system, which is why it’s best not to give them macadamia nuts at all.

It’s also best to avoid giving your terrier any nuts as some types are very harmful to their health. Walnuts, in particular, contain a toxin that may be difficult for dogs to digest, so these should never be given as a treat or part of the regular diet.

Some types of seeds are also harmful to your terrier, and they should be avoided. Pumpkin, sunflower, and sesame seeds should not be given to Yorkies because they can cause gastrointestinal irritation, leading to vomiting and diarrhea.

Spoilt Foods

There might be dangerous items in your garbage, such as rotten or moldy meals, that could make your dog sick. Molds with mycotoxins induce severe muscular shakes or tremors. Ensure that your dog does not have access to old or rotten meals, such as those in open garbage cans.

Caffeine is toxic for dogs, so you should never give your dog anything with caffeine, including coffee or tea. Caffeine can make your Yorkie very hyperactive. Caffeinated drinks are harmful to the nervous system and heart rate, so keep these out of reach.

As more people spend time at home, dogs have had more opportunities to explore the family’s pet dangers. The Pet Poison Helpline claims that there has been a 220 percent increase in calls about brewed coffee.

Fatty Foods

Feeding your Yorkie fatty foods such as fried chicken, bacon, hot dogs, or ribs can upset its stomach leading to vomiting or even diarrhea. Fatty foods may also cause pancreatitis, an inflammation of the pancreas. Contact your veterinarian if you detect symptoms in your dogs, such as:

  • Tummy discomfort
  • Inactivity
  • Inability to eat


Avocados contain a chemical called persin, which can be toxic to dogs. Avocado skin and leaves contain more persin, and other varieties have a higher or lesser amount of this hazardous chemical.


Onions are poisonous to your dog’s red blood cells, causing them to be unable to transport oxygen throughout the body; this is as fatal as it may sound. Dogs can also be sensitive to onion powder, so keep it out of reach in your spice rack.

You might be skeptical as to why a dog would consume an onion, although they’ve been seen consuming slices dropped on the ground, onion rings, and pearl onions.


Garlic, like onions, can harm a dog’s red blood cells. Like onions, you might be wondering what dog eats garlic. Dogs are capable of eating strong-tasting foods.

They might consume dropped garlic cloves while preparing a meal or get into an open jar of minced garlic. Garlic powder poses a similar problem, so be aware of where you keep it.

Excess Salt

Too much or excess salt, whether it’s served straight from the shaker or on popcorn, pretzels, potato chips, or other snacks, can cause health issues for your dog. It can lead to salt or sodium ion poisoning, which damages the kidneys. Signs include urination, vomiting, diarrhea, and excessive thirst.

Other Considerations on What to Not Feed Your Yorkie

You should avoid giving your pet any artificial sweetener as these can cause dizziness, seizures, and other neurological symptoms in dogs if they ingest too much of it at once. This includes products like saccharin, found in some types of candy, so keep these away from your terrier.

Even if they might be costly, it’s also helpful to stick to feeding them their food and treats, which are made specifically for dogs, including the Yorkshire Terrier. This includes foods like dry kibble or wet canned dog food and chews and other types of treats for dogs.

Lastly, avoid giving your terrier any human medication. It’s best to speak with a veterinarian before giving dogs anything like aspirin or ibuprofen, as these can be harmful to pets if given in the wrong dosage. Never give your pet Tylenol (acetaminophen) unless instructed by a veterinarian first.


So remember to always read the ingredients labels on pet food before giving them to your dog. Also, avoid human foods that are very high in sodium, dairy products, or other ingredients. If you have any questions about what is bad for your Yorkshire Terrier, don’t hesitate to contact a vet.
