Prof. David Walsh, Ph.D.Many common human foods pose serious dangers to dogs as a result of metabolic variations. Chocolate contains theobromine, which dogs cannot process, resulting in heart difficulties and seizures. Grapes and raisins can cause kidney failure even in small quantities. Onions and garlic can cause a breakdown of red blood cells, leading to anemia. Xylitol causes rapid release of insulin and failure of the liver.
Chocolate Toxicity
- Theobromine: Dogs metabolize 4x slower than humans
- Dark chocolate: Most dangerous with 130-450mg/oz
- Symptoms: Vomiting, rapid breathing, seizures
- Lethal dose: 100-150mg/kg body weight
Fruit Dangers
- Grapes/raisins: Unknown toxin causes kidney failure
- Cherries: Cyanide in pits and stems
- Avocado: Persin causes vomiting and diarrhea
- Citrus: Oils irritate digestive system
Other Toxins
- Xylitol: 0.1g/kg causes hypoglycemia
- Alcohol: Depresses nervous system rapidly
- Caffeine: Stimulant overdose risks
- Macadamia nuts: Neurological impairment
Recognize emergency symptoms which necessitate immediate veterinary attention. Signs of chocolate poisoning include anxiety and a rapid heartbeat. Xylitol poisoning gives sudden weakness and causes one to fall. Grape consumption decreased urine production. Pale gums exhibit onion poisoning. Keep emergency phone numbers handy, and know the address of the nearest twenty-four-hour clinic.
Take prevention measures to protect your inquisitive dog. Keep foods in locked cabinets instead of on the counter. Use pet-proof trash cans. Educate everyone in the family about poisonous foods. A helpful idea is to post a list of toxic foods on your refrigerator. Pet insurance may be a good idea in case of accidental poisoning.
Assemble a pet first-aid kit that includes hydrogen peroxide for vet-ordered vomiting and activated charcoal. Know your dog's weight to give accurate treatment, program emergency numbers on your mobile phone. At times of the year when risk is increased, supervise your dog constantly around food.
