Foods to Avoid for Dogs: A Handy Guide to Keeping Your Dog Safe

The majority of dog parents

are well aware that chocolate poses a significant danger to their beloved canine companions due to its theobromine content, which can lead to toxicity and even fatality.

However, there are numerous other human foods that also pose risks to small breed dogs.


"Onions, garlic, leek, and chives are commonly used as ingredients in many dishes due to their strong aromatic properties. In dogs, these ingredients can cause anaemia from red blood cell destruction and dogs are highly susceptible to poisoning from human food containing them, even when the food is cooked thoroughly." - Dogs Trust


Here's a list of such dangerous foods

1. Alcohol – Not only does it intoxicate dogs, but it can also cause comas or even prove fatal.

2. Avocados – Containing persin, avocados can trigger severe stomach discomfort in dogs. Additionally, the large pit can be a choking hazard.

3. Coffee – Loaded with caffeine, coffee is poisonous to dogs and must be avoided.

4. Grapes and raisins – Both highly toxic, consuming them in large quantities can lead to kidney failure in dogs.

5. Macadamia nuts – These nuts are especially harmful due to their tendency to cause weakness, vomiting, and tremors in dogs.

6. Milk and dairy products – Dogs are often lactose intolerant, leading to discomfort if they consume excessive dairy.

7. Mushrooms – Like humans, certain mushroom varieties are safe for consumption while others are highly poisonous. To err on the side of caution, it's advisable to avoid all mushrooms.

8. Onions – Thiosulphate, found in onions, damages dogs' red blood cells. Garlic, leeks, and chives, belonging to the Allium family, pose similar dangers.


"Chocolate contains a chemical called theobromine which is poisonous to dogs and other animals. Generally speaking, the darker the chocolate, the more theobromine it contains, and therefore the more poisonous it is." - The Kennel Club


In general, the ideal diet for optimum

dog health is undoubtedly one tailored to their canine needs. Opting for specialised dog foods and treats ensures the utmost safety and well-being for your furry family members.

"Xylitol (also known as E967) is a naturally occurring sweetener that is used in many food products instead of sugar, including sugar-free gum, mints, sweets, and some baked goods and peanut butter. Xylitol can stimulate insulin release in dogs, leading to a dramatic crash in blood sugar levels. It can also cause liver failure in dogs." - Dogs Trust

It's crucial for pet owners, especially those with small breed dogs, to be aware of foods that can be toxic to dogs.

If consumed by a dog, several typical human foods can be poisonous or hazardous, resulting in negative responses or major health problems.

These include chocolate, grapes, raisins, onions, garlic, avocado, caffeine, alcohol, xylitol (an artificial sweetener), macadamia nuts, and nuts like almonds and walnuts.

These foods can cause symptoms ranging from gastrointestinal upset, such as vomiting and diarrhoea, to more severe conditions like kidney failure, liver damage, seizures, or even death.

You must keep these hazardous items out of your small breed dog's reach and take them to the vet immediately if you think they may have consumed something dangerous.

What is the most toxic thing a dog can eat?

While many foods can be harmful to dogs, some substances are particularly toxic and should be avoided at all costs.

Among the most toxic substances for dogs are chocolate, xylitol (an artificial sweetener found in sugar-free products), grapes, raisins, onions, garlic, avocado, caffeine, alcohol, and certain types of nuts like macadamia nuts.

Ingestion of these items can lead to a range of health problems, from gastrointestinal upset and neurological symptoms to organ damage and failure.

To avoid accidental consumption and possible poisoning occurrences, owners of small breed dogs must exercise caution and keep certain chemicals out of their dogs' reach.

Is dog food toxic to humans? Is dog food poisonous to humans? 

Dog food is not meant for human eating, even though it is designed to suit the nutritional needs of dogs and is typically safe for canine intake.

Ingesting dog food in small amounts is unlikely to cause harm to humans, but it may not be palatable or digestible for people.

However, consuming large quantities of dog food could potentially lead to gastrointestinal upset or other digestive issues in humans due to differences in nutrient requirements and dietary composition between humans and dogs.

Additionally, some dog foods may contain ingredients or additives that are not suitable for human consumption.

It's always best to stick to food intended for human consumption and to keep pet food and human food separate to avoid any potential health risks.
