onions and garlic
anything that is part of the allium family is bad for dogs. that includes onions and garlic, as well as chives, leeks and shallots. all parts of these plants contain a toxic substance called n-propyl disulfide that damage your dog’s red blood cells, leading to anemia. according to the
american kennel club
, the dangerous effects of onions and garlic are more pronounced in powders than fresh versions, and it takes about 100 grams of onion per 20 kilos of dog to produce toxic effects.
avocados
another tasty, healthy human food that can be a
problem for dogs
are avocados. the green fruit contains a substance called persin, a fungicidal toxin, that is harmful to many animals. most of the persin in the avocado plant is located in the skin and leaves, but the flesh is still potentially poisonous for dogs, and can cause vomiting, diarrhea, and myocardial damage in large amounts.
macadamia nuts
macadamia nuts a great snack for people, but, once again, not for dogs. part of the protaceae family, macadamia nuts are one of the more
toxic foods for dogs
as they can affect a dog’s nervous system. ingesting macadamia nuts can lead to vomiting, increased body temperature, inability to walk, and lethargy. the harmful substance in these nuts is not known, but you should keep them away from your four-legged friend.
