Foods Your Dog Should Avoid

Most of us know that there are certain foods that people eat that can be dangerous for your dogs.  A perfect example of such a food would be chocolate.  But, did you know that there are a number of fruits and vegetables that are healthy for us, that may be harmful to your four-legged friend?  Following is a breakdown of eight different types of produce that can be toxic for your dog.

Grapes, Raisins and Currants

These are great HUMAN snacks but are one of the most dangerous types of foods for your pup.  For a 20-pound pup, consuming as few as four grapes or raisins can cause irreversible kidney damage.  Within hours, your dog may experience:

  • Vomiting
  • Diarrhea
  • Abdominal Pain
  • Stumbling when walking

Onions, Garlic and Chives

Eating as little as a teaspoon of powdered, raw, cooked or any other form of garlic, onions or chives can cause serious health issues for your dog.  Consuming these food items can destroy your pup’s blood cells, cause anemia and irreparable harm to their kidneys.  Symptoms to watch for after consumption of these foods is:

  • Weakness
  • Breathlessness
  • Tiredness
  • Vomiting
  • Bloody Urine


Avocado and guacamole should be kept far away from your furry friend.  An avocado tree contains persin in its fruit, leaves, seed and bark.  Persin is harmless to humans but can cause a great many dangerous side effects for your canine.  This includes:

  • Vomiting
  • Diarrhea
  • Difficulty Breathing

Persimmons, Peaches, Plums, Apricots and Cherries

Persimmon seeds can cause inflammation of the small intestines if eaten by your canine.  Likewise, the seeds or pits of peaches, plums, apricots and cherries contain cyanide.  Cyanide is a chemical that is poisonous to humans and dogs.  If swallowed by your dog, intestinal obstruction, and respiratory failure is very possible.


There are certain types of wild mushrooms that can be poisonous and sometimes fatal if consumed by your dog.  Symptoms that your canine may experience after eating a toxic mushroom can include:

  • Wheezing
  • Vomiting
  • Diarrhea
  • Changes in Heartbeat

Depending upon the type of mushroom, your dog may also experience:

  • Organ Failure
  • Seizures
  • Coma

Tomato Plants

The stems, vines, and leaves of a tomato plant may contain atropine and tomatine.  These items can be poisonous to your dog and cause the following symptoms such as:

  • Dilated Pupils
  • Tremors
  • Seizures
  • Vomiting
  • Diarrhea
  • Drooling

Additionally, if your canine eats an unripe tomato, gastronomical pain may occur.  But, eating a ripe tomato is very unlikely to cause your pet these types of issues.  If you choose to feed your dog a ripe tomato, do so in small amounts and only provide the vegetable part.  A ripe, red tomato is the safest for your furry friend.


Humans and dogs should never eat raw potatoes if they are green or have a green rim.  Raw and green potatoes may contain solanum alkaloids (solanine).  This can cause the following symptoms in your pet:

  • Vomiting
  • Diarrhea
  • Irregular Heartbeat

Just like tomatoes, raw potatoes contain harmful oxalates that can cause kidney, digestive tract and nervous system problems for your dog.


Rhubarb also contains oxalates.  Consuming this plant may cause the following problems:

  • Nervous System
  • Digestive Tract
  • Kidneys

Rhubarb may also reduce the calcium in your dog and cause renal failure as well as other health issues.

In an Emergency

If your furry canine friend has consumed any of these types of foods, you should take him to the vet or an emergency clinic immediately.  Your vet or animal care professional will be able to prescribe an appropriate treatment like oxygen therapy, blood transfusions or induced vomiting.
