10 foods for your dog to AVOID, and their symptoms.


We have created a top 10 list of foods and items that your dog should avoid through life. This could be due to them being poisonous or very unhealthy for their consumption. If you are unsure about anything that is not on this list then please contact your local vet for clarification.


(In no particular order)

1. Chocolate

Most people know that a dog eating chocolate is not good, but they don't know why. Well they are correct that chocolate is not safe for dog consumption and this is due to a component in chocolate called theobromine and caffeine as well. The darker the chocolate the more theobromine it contains.


Symptoms of chocolate consumption include :

- Hyperactivity 


- Diarrhoea

- Seizures

- Unusual heart rate 


2. Bones

Although the common phrase 'give a dog a bone' would suggest that bones are good for dogs, on the contrary they can actually cause damage to a dogs stomach. This happens when a dog consumes a splinter that has come off the bone and can obstruct the bowels or damage the stomach and intestines. This can lead to a fatal stomach infection.

Not all bones will produce splinters when being chewed but it is definitely something to watch out for.


Symptoms of splintered bones include :

- Tender abdomen

- Vomiting

- Loss of appetite

- Diarrhoea 

- Blood in faeces


3. Sweets and surgery foods

 Dogs, much like humans, can get tooth decay and gain weight by consuming sweets and other processed sugary goods. The only difference is that it takes a lot less for the problems to set in and can become very costly with vet bills if not dealt with and removed from their diets. They are just worth avoiding altogether.


Symptoms of sweet consumption include :

- Vomiting

- flatulence

- all round discomfort 

- diarrhea  


4. Alcohol

Although it seems obvious not to give your dog a beer and they probably wouldn't drink it any way its good to know for sure that dogs should not be consuming alcohol as they are some times attracted to fruit based drinks. Non the less any alcoholic beverages or foods are toxic and should be kept away.


Symptoms of alcohol toxicity include:

- depression

- drooling

- incoordination

- vomiting 

- weakness 

- collapse

- decrease breathe intake/ outtake rate



Your day may start with a coffee or energy drink but your dogs should definitely not. Although this may seem obvious not to make your dog a coffee sometimes its better to be safe then sorry to include it on this list just in case that situation ever happens, so now you know. Caffeine contains a stimulant which is toxic to dogs and should be avoided. 


Symptoms of caffeine intoxication include :

- Shaking

- Hyperactivity

- Seizures

- Agitation

- Panting

- Hypothermia


6. Grapes

Most people know that you should not give a grape to a dog but most people also don't know the reason why. Grapes and raisins should be avoided as they can cause kidney failure in a percentage of dogs on consumption. This does not happen for every dog it should be noted but I would say it is not worth the risk to try.


Symptoms of grape consumption include :

- Vomiting

- Lack of appetite 

- Lethargy

- Diarrhea


7. Salty foods

Too much salt in a dogs diet can cause dehydration and even sodium ion poisoning which is definitely something to avoid. Small amounts of salt that a dog consumes is nothing to serious worry about but should be kept to a minimum.

Symptoms of excessive salt consumption include :

- Lack of coordination 

- Excessive drinking and urination 

- Diarrhea

- Tremors and seizures

- Vomiting

- Lethargy 


8. Milk

 A dog lacks the enzyme lactase which helps break down milk in their stomach so they can digest it. This means that it is overall something that should be avoided after the stages of puppyhood when they are consuming their mothers milk. In small doses are with moderation it should not cause any major damage, however if not consumed in moderation it can lead to diarrhea and discomfort.


Symptoms of excessive milk consumption include :

- Diarrhoea

- Vomiting

- Abdominal pain

- Bloating

- flatulence 

9. Onions and garlic 

Onions and garlic are on most dinner plates every night across the country, but don't let your dog finish off your left overs. This is because they can cause anaemia by killing off your dogs red blood cells. A small amount in certain dogs can have horrendous consequences.


Symptoms of onion and garlic intake include :

-Reduced appetite

- Vomiting 

- Diarrhoea


10. Avocado 

Throughout, Avocados consist a strain of fatty acids called persin. This is highly toxic animals as a whole but less so for dogs according to recent data from the ASPCA. That does not however make them 100% safe and we would recommend leaving them out of your dogs diet as they have been known to cause problems.


Symptoms of avocado consumption include :

- Upset stomach

- Unrest


If you are unsure about something that you dog has eaten or you are looking for symptoms to compare to what your dog is showing then please contact your vet for clarification as it is always better to be safe then sorry, especially with your furry best friend.
