foods poisonous to dogs - 10 human foods dogs should not eat

What’s Delicious To Humans Are Toxic To Dogs

Feeding human foods poisonous to dogs can be very dangerous for their health and may even be life-threatening.

Unlike humans, dogs have a different metabolism. It is important to keep foods poisonous to dogs out of their reach. In the event that your dog consumed any of these harmful foods, visit the vet immediately.

01 - grapes and raisins

It takes only one tiny grape or raisin to make a dog very sick. These fruits can cause kidney failure in dogs.

Beware of these fruits found in bread, rolls, and cookies which a dog can accidentally eat. Canines that already have underlying health problems are at greatest risk and just one raisin can be lethal.

02 - chocolate

Chocolate contains a caffeine-like stimulant called theobromine that is poisonous to dogs.  The darker the chocolate, the higher the amount of theobromine it contains. Rule of thumb, dark chocolates are the most dangerous.

Signs of theobromine poisoning will occur between four and 24 hours after ingestion.  Signs to look out for are vomiting, diarrhoea, restlessness, hyperactivity and seizures.

Caffeine is not only found in coffee but in tea bags too.

04 - onions, garlic, chives and leeks

Onions are particularly poisonous to dogs. Eating these vegetables can cause stomach and gut irritation and lead to red blood cell damage and anaemia.

Signs of poisoning often only occur a few days after your dog has eaten raw or cooked onions. Look out for table scraps containing cooked onions or garlic, pizza and cooked dishes.
