Most dangerous thanksgiving food for your pet:

WHAT NOT TO FEED YOUR PET

1. Grapes & Raisins: Can result in severe acute kidney injury.
2. Xylitol (Found in Baking Goods): When ingested by dogs, it can result in a massive insulin spike, causing a life-threatening hypoglycemia (low blood sugar) and even liver failure with higher doses.

3. Fatty Table Scraps (gravy, turkey skin, etc): Potentially dangerous to your dog, as they can result in severe pancreatitis.

​4. Bones & Turkey Legs: Risk for a possible foreign body obstruction. The bones can also get stuck in the stomach or intestines, potentially resulting in a perforation (or rupture) of the intestines.

5. Onions, Leeks, Chives and Garlic: Can result in oxidative damage to the red blood cells, making these cells more likely to rupture (e.g., hemolyze). Cats are especially sensitive, and can develop a severe anemia (low red blood cell count) from even small amounts. This is typically seen more with chronic ingestion (e.g., when they are eating it for days), but to be safe, keep these out of reach.​

6. Unbaked Yeast Bread Dough: Your dog’s stomach acts like an artificial oven, making the yeast rise and release carbon dioxide, causing a distended abdomen and potential life-threatening gastric dilatation-volvulus (GDV). Next, the yeast and sugar in the unbaked dough are metabolized to alcohol, which can result in secondary alcohol poisoning in your dog
7. Alcohol: Accidental ingestion can cause severe coma, slowed respiration, and a life-threateningly low blood sugar in your dog.​
