Teach your dog to chew *only* his/her toys.

Watch what your dog eats in the garden; even be careful of the stick you pick up to throw for the dog while in the woods.

Symptoms: (may include some or all) trembling, abdominal pain (may be evident by hunch back, rigid stance with whining), rapid breathing, vomiting, convulsions, depression and coma.

These may occur rapidly or over a period of many hours, depending on the cause. If poisoning is suspected, induce vomiting *AT ONCE*. A most effective method is to administer about a teaspoon per 5 pounds of body weight, of HYDROGEN PEROXIDE by mouth. If vomiting does not occur within 5 to 10 minutes, the dose may be repeated at least 2 more times.

Example: A husky may require 3 tablespoons and 1 teaspoon of hydrogen peroxide, if the husky weighs 50 pounds.


Also check with your veterinarian about what common wild flowers are in your area. If you suspect toxic plant poisoning, take the plant and your dog to your vet so that she/he might have a better chance in selecting the right antidote.

Some other common poisonous substances for your dog are grapes, raisins, and chocolate. Remember to put presents containing chocolate out of the reach of dogs! Often a dog will smell the chocolate in a present under a Christmas tree, open it, and eat all the chocolate. Even wrapping chocolate does not hide it from your dog.

Dogs like grapes and raisins, because the sugar attracts them. These are poisonous to your dog, so please make sure your dog has no opportunity to eat them. Onions also are in this category, and they are especially attractive to your dog when fried.
