Onions and garlic are also common pickling ingredients. These are from the allium family of root vegetables and include leeks, scallions, and chives. These vegetables contain n-propyl-disulfide, an organic compound that damages your dog’s red blood cells and causes hemolytic anemia in dogs. The organosulfur compound, found in allium plants, attaches itself to hemoglobin, the oxygen-carrying protein in the blood, creating Heinz Bodies. These damaged red blood cells (Heinz Bodies) die off more quickly than your dog’s body can replace them, leaving your dog with anemia. Signs of anemia include extreme fatigue, loss of appetite, and kidney damage. It’s a serious condition that requires immediate veterinary care. Vinegar damages dogs kidneys. Don't feed your dog fucking dill pickles moron. It's not a human.
