Why Pepper Jack needs caution
Monterey Jack itself is a standard low-lactose, moderate-fat cheese. The embedded chilies bring capsaicin, which dogs have no tolerance for: expect drooling, lip-licking, and stomach upset rather than true poisoning. Some brands also add garlic or onion flecks, and Alliums damage canine red blood cells, which is a genuine toxicity rather than an irritation.
