Although cheese curds may not be toxic for dogs, their bodies cannot digest lactose after puppy-hood. This means that a food high in lactose, such as cheese curds, may cause diarrhea, vomiting, and gassiness. If your dog overfeeds on cheese curds, he may suffer obesity, pancreatitis, hypertension, and other heart-related issues. You should monitor your dog when eating cheese curds, especially if he has a preexisting condition like diabetes.
