Yes, they can. However, jalapeno chips might not be the best snack for your dog.  While some overweight dogs may be able to consume jalapeno chips, it’s safer to provide them with plain crackers instead. If you give your puppy too many jalapeno chips, it might get fat and develop stomach issues. Overweight dogs should avoid eating these spicy snacks because they can aggravate an already sensitive stomach and cause gas or diarrhea. Jalapeno chips have capsaicin which can irritate the digestive system and cause an upset stomach in dogs. Feed your dog plain boiled chicken breast or a cooked hot dog instead of jalapeno chips. Too much salt in these chips and other hazardous chemicals like capsaicin can harm your dog.
