In order to properly home-cook for your pets though, you should first have a basic knowledge of canine nutritional needs being that dogs can develop many of the same diseases that we can. My dog was just diagnosed with diabetes and is currently on a keto diet! And, even more important, a thorough knowledge of human foods that are toxic to your dog.

Some foods which are safe for humans can be poisonous for our canine companions. It’s especially important to watch out for these especially around the holidays when we and others around us don’t have our guard up as much or well meaning, unknowing friends may give our furry friend a hand out that perhaps may be harmful for them.

Here is a list of 25 common human foods that are toxic to dogs.

When in doubt, always check with your vet.

  1. Onions, Garlic, Chives (Both onions and garlic contain the toxic ingredient Thiosulphate. But onions are more of a danger. Can lead to red blood cell damage.

Many dog biscuits contain *small* amounts of garlic – garlic contains less of this toxin so huge amounts would need to be consumed to be toxic. And, by the way, this poison builds up the system – it can be toxic in one large dose – or with repeated consumption of small amounts.)

2) Chocolate (Chocolate contains Theobromine, a compound that is a cardiac stimulant and a diuretic. This can be fatal to dogs.)

4) Raisins (See above.)

5) Most Fruit Pits and Seeds (Contain Cyanogenic Glycosides resulting in cyanide poisoning – though the fruit itself is OK.)

6) Macadamia Nuts (Macadamia nuts contain an unknown substance that is toxic to dogs.) they can cause weakness, depression, vomiting, tremors and hyperthermia in dogs. Signs usually appear within 12 hours of ingestion and can last approximately 12 to 48 hours.

Other nuts, including almonds, pecans, and walnuts, contain high amounts of oils and fats. The fats can cause vomiting and diarrhea, and potentially pancreatitis in pets.

7) Most Bones should *not* be given (especially chicken bones) because they can splinter and cause laceration of the digestive system and/or become lodged in your pet’s throat – so they also pose a choking hazard.

8) Rhubarb – The stalk is not considered toxic but the leaves are and can lead to kidney failure.

Rheum rhabarbarium, commonly referred to as rhubarb, is a herbaceous perennial with fleshy red stalks and large triangular leaves. All parts of the rhubarb plant contain soluble calcium oxalate crystals, although they are concentrated in the large leaves. Oxalate crystals can cause intense pain and irritation when chewed or swallowed.

This irritation, combined with an unpleasant taste, usually prevents animals from doing more than sampling the plant. However, some pets will work past the pain as they chew and on rare occasions, a dog may eat larger amounts of plant material.

9) Broccoli (Broccoli is only toxic in large quantities.)

10) Green parts of Tomatoes or Green Potatoes(Contain oxalates, which can affect the digestive, nervous, and urinary systems.) Potato Peelings too (Contain Oxalates, which can affect the digestive, nervous, and urinary systems.)

11) Yeast Dough (Yeast Dough can produce gas and swell in your pet’s stomach – leading to rupture of the digestive system) This can be painful and can cause the stomach to bloat, and potentially twist, becoming a life threatening emergency. The yeast produce ethanol as a by-product and a dog ingesting raw bread dough can become drunk. (see alcohol)
