When you ask someone “What foods are toxic to dogs?” chocolate is often the first to come to mind. Chocolate toxicity can cause vomiting, diarrhea, heart arrhythmias and seizures, and can even be fatal. This is due to an ingredient in chocolate called theobromine, which can be poisonous to pets. The darker the chocolate and the smaller the dog, the greater the danger. Consult your veterinarian if your dog eats any.
Tails wag at the scent of greasy and high-fat cheeseburgers, bacon and fried foods, but don’t give in to their begging. While these foods aren’t toxic, consumption can lead to vomiting, diarrhea and gas, and can result in pancreatitis and gastrointestinal issues.
No more rewarding your pet with fat trimmed from your steak, chicken or pork. You run the risk of causing pancreas and liver problems. Be cautious of leftover bones, too; cooked bones are more likely to splinter, and the sharp pieces of bone can tear digestive organs and cause internal bleeding.
Onions and garlic can be lethal because of an ingredient called thiosulphate, which can damage your pet’s red blood cells and cause anemia. Thiosulphate is found in onions, shallots, chives and onion powder. It’s especially potent in garlic.
Cooked eggs can make a healthy addition to your dog or cat’s diet, if eaten in moderation. Excessive consumption of raw eggs, however, can lead to a biotin deficiency that is bad for dogs’ skin and fur.
Dogs love the taste of almonds, particularly the flavored variety (jalapeno, barbecued, smoked, vanilla, cinnamon, etc.).
While not toxic, almonds are not easily digested can give your dog an upset stomach and create gastric intestinal distress.
Black walnuts contains a toxin called juglone which can cause a vascular disease in horses known as laminitis, but doesn’t appear to cause problems in dogs. Eating black walnuts can cause gastric intestinal upset or an obstruction.
In addition, moldy black walnuts can contain tremorgenic mycotoxins which can cause seizures or neurological symptoms.
English walnuts can cause gastric intestinal upset (tummy ache) or even an obstruction in your dog’s body.
Like black and Japanese walnuts, moldy English walnuts can contain tremorgenic mycotoxins (toxic chemical products produced by fungi) which can cause seizures or neurological symptoms.
Hickory nuts also contain the toxin juglone that can cause laminitis in horses. Eating hickory nuts can cause the same problems associated with black walnuts: gastric intestinal upset or an intestinal obstruction.
Like walnuts, moldy hickory nuts can contain tremorgenic mycotoxins which can cause seizures or neurological symptoms.
Japanese walnuts contain no toxicity; however, they can cause gastric intestinal upset or even an obstruction.
Like English walnuts, moldy Japanese walnuts can contain tremorgenic mycotoxins which can cause seizures or neurological symptoms.
Macadamia nuts are very rich in fat which can give your dog a major upset stomach and may cause pancreatitis.
In addition, these nuts are reported to contain an unknown toxic principle that may result in neurological symptoms.
Pecans also contain the toxin juglone that can cause laminitis in horses. Feeding dogs pecans can cause gastric intestinal upset or an obstruction.
Like walnuts, moldy pecans can contain tremorgenic mycotoxins which can cause seizures or neurological symptoms.
Pistachios are also rich in fat and can cause your dog to develop an upset stomach. In addition, repetitive eating of pistachios can cause pancreatitis in your dog.
While not inherently a food poisonous to dogs and cats, raw fish may contain harmful bacteria that can lead to food poisoning in your pet. In addition, your pet may also be at risk of catching “fish disease” due to a parasite commonly found in salmon, trout, sturgeon and other upstream-swimming fish. Be sure to monitor your pet closely during fishing trips or at the beach.
A pretzel here or a potato chip there is mostly harmless. But large quantities of salt can lead to salt poisoning, which has severe neurological symptoms, including seizures and brain swelling. Be sure to monitor your pooch at the beach, since drinking salty ocean water is a common cause of salt poisoning.
If your dog or cat can roam your yard, remove any wild mushrooms. The wild variety typically causes the most harm, as opposed to grocery store mushrooms. Even a few bites can cause seizures and vomiting.
The large seeds found in avocados can become lodged in your pet’s stomach, esophagus or intestinal tract. If you live near avocado trees, be sure to monitor your pet to prevent choking.
Grapes and raisins can cause kidney issues in dogs and cats. Even small amounts can result in lethargy, shivers and a decreased appetite. More extreme cases of grape poisoning can cause kidney failure and even death.
These fruits are toxic to dogs and cats, causing dilated pupils, breathing problems and, in extreme cases, shock or even death. Beware of cherry trees and shrubs as well. With the exception of the ripe pulp around the seeds, these plants are poisonous to pets, as the non-pulp parts contain cyanide.
Beware of fruits with pits. They can cause your pet to choke or obstruct their intestines, particularly plum and peach pits, which also contain poisonous cyanide.
