Dog poison No. 4: Chocolate. Though not harmful to people, chocolate products contain substances called methylxanthines that can cause vomiting in small doses, and death if ingested in larger quantities. Darker chocolate contains more of these dangerous substances than do white or milk chocolate. The amount of chocolate that could result in death depends on the type of chocolate and the size of the dog. For smaller breeds, just half an ounce of baking chocolate can be fatal, while a larger dog might survive eating 4 ounces to 8 ounces, though 8 ounces would be extremely da n gerous. Coffee and caffeine have similarly dangerous chemicals.

Dog poison No. 5 Veterinary products -This includes medications as well as flea and tick treatments. Just as we can be sickened or killed by medications intended to help us, cases of pet poisoning by veterinary drugs are not uncommon. Some of the more commonly reported problem medications include painkillers and de-wormers. And you may think you’re doing your dog a favor when you apply products marketed to fight fleas and ticks, but thousands of animals are unintentionally poisoned by these products every year. Problems can occur if dogs accidentally ingest these products or if small dogs receive excessive amounts. Talk to your vet about safe OTC products.

Dog poison No. 6: Household products, from cleaners to fire logs. Just as cleaners like bleach can poison people, they are also a leading cause of pet poisoning, resulting in stomach and respiratory tract problems. Not surprisingly, chemicals contained in antifreeze, paint thinner, and chemicals for pools also can act as dog poison. The pet poisoning symptoms they may produce include stomach upset, depression, chemical burns, renal failure and death.

Dog poison No. 7: Rodenticides - Unfortunately, many baits used to lure and kill rodents can also look tasty to our pets. If ingested by dogs, they can cause severe problems. The symptoms depend on the nature of the poison, and signs may not start for several days after consumption. In some instances, the dog may have eaten the poisoned rodent, and not been directly exposed to the toxin.
