October 25, 2004 Toxic Foods for Dogs? Provided by

Q: Is it true that chocolate is deadly for dogs and that grapes and raisins can make dogs sick? -- Jon R. A: Chocolate can be deadly for certain dogs, but the size and breed of the dog and the amount of chocolate consumed determine how sick a pooch can get. Grapes and raisins are a different story - very small amounts can lead to kidney failure in some dogs.
Chocolate contains theobromine, a drug that is in the same family as caffeine and theophylline (found in tea). Some dogs are very sensitive to it.
So far, however, vets haven't been able to determine what it is about grapes and raisins that make them so dangerous. They've looked at the chemistry of grapes and raisins and at possible residues of pesticides, heavy metals, fertilizers, and other chemicals that may have been used in cultivation, but no chemical culprit has emerged.
As far as chocolate is concerned, you don't have much to worry about if your pet snags a piece of candy. Toxic reactions generally don't develop unless a dog ingests 100-150 milligrams of theobromine per kilogram of its weight. That would average out to about an ounce of chocolate per pound of body weight for milk chocolate. Semisweet and Baker's chocolate contain more theobromine so the rule here is one ounce per three pounds of body weight for semisweet chocolate and one ounce per nine pounds of body weight for Baker's chocolate.
Symptoms of chocolate toxicity in dogs include hyper-excitability, hyper- irritability, increased heart rate, restlessness, increased urination, muscle tremors, vomiting, and diarrhea. There is no specific antidote, but if you believe your dog has eaten too much chocolate, take him to the vet as soon as possible for treatment of the specific symptoms. Just to keep things in perspective, I might mention that my daughter's Welsh Corgi once consumed seven chocolate oranges in a raid on a Christmas stash in a closet; she had nothing worse than diarrhea for a few days.
In 1989 the ASPCA's Animal Poison Control Center (APCC) began tracking a trend which showed that dogs who ate grapes and raisins developed kidney failure. The type of grapes or brand of raisins doesn't matter. Neither do the amounts the dogs ate: these can vary from more than a pound of grapes to as little as a single serving of raisins.
After eating grapes and raisins, dogs typically vomit within a few hours and then stop eating and develop diarrhea. Then they become quiet and lethargic, and show signs of abdominal pain. These symptoms can last several days -- sometimes even weeks. Blood tests can reveal changes in kidney function so if you know or suspect that your dog has eaten either grapes or raisins, get him to the vet immediately. Treatment can save his life.

October 29, 2004 Can You Get High on Hemp Seeds? Provided by

Q: If I eat foods containing hemp will I test positive for drugs? -- J. Polk A: Even if you ate nothing but foods containing hemp, you wouldn't test positive for drugs. Hemp foods do contain trace amounts of tetrahydrocannabinol (THC), the substance in marijuana that is responsible for the "high" you can get by using the drug. But the minuscule amounts of THC in hemp seeds or the bread, cereals, granola bars, beer and other products made from them will not alter drug tests.
This issue was hotly debated in a recent court case. The manufacturers of hemp foods fought a Drug Enforcement Administration (DEA) rule banning the use of hemp seed or oil containing traces of THC in any foods. In February of 2004, the Ninth Circuit Court of Appeals overturned the DEA rule and held that hemp seeds and oil used in foods couldn't be defined as drugs.
The decision was a victory for consumers because healthy hemp foods may now become more widely available. Many retailers had been reluctant to carry hemp food products as long as the legal case was undecided. Hemp seeds and oil are great sources of omega-3 fatty acids, protein, and fiber. They also provide vitamin E. Look for more hemp foods in the market now that the court case has been resolved.
I recommend eating whole hemp seeds as a good source of omega-3 fatty acids. They're delicious and very easy to prepare. Just pour half a cup of them into a dry skillet placed over medium-high heat and stir them around until they begin to toast and pop. At that point, turn off the heat, stir in a teaspoon of olive oil and then season with salt and pepper or a little soy sauce, red pepper, garlic powder or herbs and eat them as a snack. Prepare only as much as you can eat since the cooked seeds don't keep well.
