5 Human Foods Dogs Should Never Eat

5 Human Foods Dogs Should Never Eat

1. Milk


Yes, puppies drink milk from their mothers after they are born. However, dogs can also suffer from lactose intolerance. Milk contains certain sugars that dogs don’t have the enzymes to break down.

What Milk Can Do

If a dog were to drink milk the side effects could include vomiting, diarrhea and other gastrointestinal problems. While it’s not critically life-threatening, it can contribute to serious bacterial exposure in dogs that could eventually lead to disease.

2. Onions


While onions may pair well with a cheeseburger that your dog would salivate over, they can do more than just make your dog shed some tears. Onions contain compounds that can be harmful to dogs if ingested enough.

What Onions Can Do

Onions can damage red blood cells in dogs which may lead to them becoming weaker and more lethargic. If enough onions have been consumed, serious problems could arise including a blood infusion.

3. Apples

You know what they say, an apple a day keeps the doctor away….not the case when it comes to dogs! The core of an apple is especially toxic to them. The core contains cyanogenic glycosides otherwise known as cyanide.

What Apple Cores Can Do

Symptoms may include dizziness, struggling to breath, seizures, collapsing, hyperventilation, shock and even coma…all from eating an apple core. Make sure to not leave them laying around for your pup to gobble up!

4. Avocado

You may want to hold off on the guac and chips when it comes to your dog. The leaves, its, bark and fruit contain a certain toxin called persin.

What Avocado’s Can Do

The effects of the toxin is different from dog to dog. Most symptoms include upset stomachs, breathing difficulties and choking caused from swallowing the pit.

5. Caffeine


While 72% of adults consume at least 2 cups of coffee per day, dogs should be left out of the equation. Coffee contains a stimulant, Methylated Xanthine.
