Plants and Foods that Could Kill Your Dog

Although many of us think of Fido as a part of the family, our beloved pooches cannot eat the same things we do. Our bodies are affected differently by various foods. In addition, curious dogs can ingest potentially harmful plants. Learn about what foods and plants are poisonous to your dog.

Dangerous foods
Although many humans love chocolate, it is not recommended that we share our favorite dessert with our dogs. Chocolate is one of the most toxic foods for dogs. It contains theobromide, which can cause breathing problems, heart palpitations, stomach pains, tremors, fever, vomiting, diarrhea, seizures and coma.

Chocolate does not always affect a dog immediately. The symptoms may not appear for several hours. After 24 hours have passed without medical attention, the end result can be death. Baking chocolate and cocoa powder are the most dangerous forms of chocolate. Even a small amount can be deadly, especially smaller dogs.

Garlic and onions are also dangerous to dogs. They contain a deadly ingredient called thiosulfate. Onions are the more dangerous food, causing anemia, diarrhea, vomiting, breathing problems, liver damage and change in color of the urine. These symptoms may occur as late as two days after eating the onion.

All types of onions can cause problems, whether they be cooked or raw, or in leftover pizza or Chinese food. Even human baby food can cause health problems in dogs. Garlic can also cause problems, but only if eaten in large amounts.

Mushrooms are also highly toxic and can be fatal, especially if certain types are eaten. In the United States, amanita phalloides is the most poisonous mushroom species. It can cause excessive drooling, stomach pain, vomiting, diarrhea, convulsions and kidney and liver damage. In severe cases, it can even cause coma or death.

Grapes and raisins can also be harmful to dogs. Although it is possible that just a few grapes or raisins could cause poisoning in dogs, the amounts in recent cases were fairly large, ranging from 9 ounces to two pounds. They can cause stomach pain, vomiting and diarrhea.

Nuts, especially macadamia nuts, can also be poisonous to dogs. They contain a high amount of phosphorous, which can lead to bladder stones, weakness, paralysis and excessive panting. Their limbs can also become swollen, making them unable to move.
Some other foods to avoid feeding your dog include:

  • Fish – Eating raw fish can result in vitamin deficiencies, seizures and even death. The bones from fish can become lodged in the dog’s throat, causing breathing problems. They can also cause obstructions in the digestive system.
  • Cat food – Cat food does not contain the right amounts of nutrition for dogs. It is too high in fats and protein.
  • Raw eggs – Although many dog owners like to mix in eggs with their dog’s dry food, they are advised against it. Raw eggs can decrease the absorption of certain vitamins, which can lead to problems with a dog’s skin or coat. In addition, raw eggs may contain salmonella.
  • Dairy products – Milk and other dairy products contain lactose, which is difficult for a dog’s body to digest properly. This can lead to diarrhea.
