“Lemon tree very pretty and the lemon flower is sweet
but the fruit of the poor lemon your dog should never eat.”

By Leslie, Carna4 Communications

Many dogs, particularly puppies, will eat just about anything — if they can reach it. Some foods offer nourishing virtues to humans but can strike disaster in a canine’s stomach.

There are plenty of lengthy lists extolling what foods and other items your pooch should avoid. Some of them include debatable items, such as spices, as well as foods, such as raw food (meat) or eggs, which if handled properly are fine.

According to multiple lists, here is a summary of most of the foods/items that can be harmful to your dog, grouped in categories to make them easier to remember.

Forbidden Fruits:

  • Avocado fruit, leaves, seeds and bark contain persin, which can be toxic and cause vomiting and diarrhea.
  • Apricot stems, leaves and seed/stone – can cause vomiting and loss of appetite.
  • Blackberries, Elderberries & Cherries – These berries, particularly unripe chokecherries, as well as their leaves and stems, can be toxic.
  • Grapes & Raisins – Even a few can make a dog ill and can cause kidney damage.
  • Lemons, Limes, Oranges & Grapefruit – Avoid all citrus fruits because their oil extracts are toxic to dogs.
  • Persimmons, Peaches & Plums – Persimmon seeds can inflame a dog’s small intestine. And these seeds, as well as peach and plum pits can obstruct their digestive tract. Peach and plum pits also contain cyanide, which is poisonous.
  • Rhubarb leaves contain oxalates, which can harm the nervous, digestive and urinary systems.

Garden Traps

  • Caster Beans are thought to be toxic to dogs.
  • Chives and Onions can cause gastrointestinal irritation and lead to red blood cell damage, if a large amount is consumed.
  • Mushrooms – As with humans, certain species are toxic and can affect multiple systems and lead to death.
  • Potatoes – Avoid raw potatoes, their stems and leaves but a slice of baked is fine.

Pantry & Kitchen Perils

  • Almonds – Avoid large quantities because they can cause digestive upset.
  • Macadamia & Walnuts – Raw or roasted, these nuts can make dogs seriously ill. Due to high phosphorus content, macadamia nuts might also cause bladder stones.
  • Salt – Dogs require a minimal amount of salt in their diet but large amounts can produce excessive thirst and urination or even sodium ion poisoning.
  • Yeast Dough – Avoid this, as it can rise and cause gas to build up in the digestive system – causing pain and potentially, stomach/intestine ruptures.

Toxic Sweets & Treats

  • Candy, Gum, Baked Goods & Toothpaste – These items and even some diet foods are sweetened with xylitol, which can increase the body’s insulin and lead to liver failure.
  • Cocoa & Chocolate – Contains caffeine and theobromine, which can cause vomiting, diarrhea and even death. Cocoa powder is the most toxic, followed by cooking, dark, semi-sweet, milk and white chocolate.
  • Fat Trimmings – Avoid these, as they can cause pancreatitis.

Human Vices to Avoid

  • Beer, Wine, Liquor & Hops – Alcohol and foods containing it, as well as hops (in most beers) can cause illness and even death. The smaller the dog, the more severely they’ll be affected.
  • Coffee, Tea, Cola & Energy Drinks – Avoid drinks containing caffeine, which in very large quantities can be fatal. Symptoms range from restlessness to fits and bleeding.
  • Marijuana – If ingested, marijuana can cause: in coordination, heart rate changes, vomiting, diarrhea, hyper salivation, seizures and coma.
  • Tobacco – Contains nicotine, which affects the nervous and digestive systems.

Others’ Territory

  • Baby Food – Can contain onion power and can also lead to nutritional deficiencies, if eaten in large amounts.
  • Cat Food should be avoided as it is generally too high in proteins and fats.
