My pug farting a lot while sleeping

Your pug's increased farting during sleep is often normal, caused by relaxed muscles, slower digestion, and potential food-related issues like food intolerances, diet changes, or difficulty digesting certain ingredients like beans, peas, or dairy. Swallowing air from eating too fast is also a common cause. However, if you notice other symptoms like diarrhea, vomiting, or weight loss, consult your veterinarian to rule out underlying health issues such as parasites, inflammatory bowel disease, or other gastrointestinal problems.
