What does chocolate, grapes and calla lilies have in common? They are all potentially deadly for your dog.

When you first get your new dog, you are usually aware of the basic needs of a bowl for fresh water available at all times, dog gates to prevent accidents from falling down stairs, or to isolate the new dog in a safe environment. Are you aware, however, of other, common household items that could be seriously harmful to your pet?

Household plants are beautiful to look at but can injure or even kill your dog if ingested. Some of the more common deadly houseplants include :

1) The philodendron. All parts of this common houseplant are poisonous. If eaten, this plant can cause swelling of the mouth and throat and damage the kidneys. If your dog eats enough, it could kill him. This plant is poisonous for children, also.

2) Peace lilies, calla lilies, and pothos can have the same deleterious effects as the philodendron.

3) Some plants used for live holiday decorations can be deadly. The yew bush produces beautiful red berries which can lead to seizures, coma and even death if eaten. Mistletoe berries are toxic for animals. They cause diarrhea, vomiting, pain, and could make your dog loose consciousness and comatose. Use artificial decorations; they'll last longer and your pets will be safer.

4) Poinsettia: There has been much controversy over this plant and whether or not it is poisonous for dogs. It can cause mouth irritation and stomach pain, so why have it within reach of your dog?

5) Dumb Cane: A pretty green plant, known for its foliage, this plant should be known to dog owners for its ability to seriously injure your pet. The dumb cane can cause mouth irritation, stomach upset, asphyxiation, seizures and death.

We always love to give our dogs little bites or treats of human food, but sometimes food that is fine for humans to eat can be deadly for dogs.

1) Chocolate: Chocolate has an ingredient called theobromine, which can cause epileptic seizures in dogs prone to seizures, or it could cause the heart to go into an abnormal rhythm leading to a heart attack, or even internal bleeding from intestinal irritation which can lead to death. The amount of chocolate eaten, and the size of the dog will determine the outcome.

2) Grapes and Raisins: Dogs can choke on grapes and asphyxiate Raisins and grapes are also poisonous for dogs.

3) Onions and Garlic:: If eaten raw, onions or garlic can cause the red blood cells to break down, leading to hemolytic anemia.

4) Nuts: Nuts are not good for dogs to eat. Walnuts are poisonous and other nuts can lead to bladder stones.
