1. Many people give this fruit to their dogs as a treat. However, just a few bites can cause fatal kidney failure in some dogs.
*Grapes
Both grapes and raisins can be toxic. Some dogs eat them with, seemingly, no ill effects. However, some dogs become ill after ingesting only a few grapes or raisins. The first symptom is vomiting, followed by acute kidney failure, from which many dogs do not recover. As of yet, the toxin is unknown, nor do we know why some dogs become sick and others eat grapes or raisins without a problem.
2. Which raw fish can cause poisoning in dogs?
*Salmon
Salmon and trout can be infected with a parasite called Nanophyetus salmincola, a type of trematode worm. The worms themselves can be infected with a type of bacteria known as Neorickettsia helminthoeca. The bacteria only infects canids; other animals show no symptoms from eating it. When dogs eat raw fish infected with this bacteria, they can show symptoms including weakness, vomiting, loss of appetite, swollen glands, and fever. Ninety percent of untreated dogs die. Cooking kills the worm and the bacteria.
3. This food is sometimes used to season dogs' meals, but can cause anemia.
*Onions
Onions and garlic contain a chemical called thiosulfate. When ingested either in large quantities or in small quantities over a long period of time, they can cause an anemia called Heinz body anemia. This is reversible if you stop feeding the onions or garlic.
4. In some dogs, this sweetener can cause hypoglycemia.
*Xylitol
This toxicity usually occurs when dogs eat large amounts of sugar-free candy or gum. In humans, xylitol does not cause a drop in blood sugar; in dogs it does. This can lead to weakness, staggering, and other symptoms of hypoglycemia. There is also some evidence that some dogs may develop liver failure after ingesting xylitol.
5. Dogs- especially dogs that are fed a straight diet of dry food with little variety- may get an inflammation of the pancreas called "pancreatitis" if they eat certain foods that they are not used to. Which of the following is most apt to cause pancreatitis?
*Turkey skin
In dogs, pancreatitis often results from eating a very high-fat meal. While dogs that are used to eating a high-fat diet, like sled dogs, can eat pure fat with no problems, dogs that are not used to such foods often cannot. When such a dog eats a high-fat meal, its pancreas overproduces enzymes, to the extent that they actually begin to "digest" the pancreas and inflame it. Common culprits are turkey skin and ham fat. Symptoms include vomiting and stomach pain. This is a medical emergency, and such dogs must be treated by a vet. Some breeds, like miniature schnauzers, are genetically predisposed to pancreatitis.
