If your dog has frequent skin rashes or infections, a dull coat, ear infections, food sensitivities, gas, dry, segmented or soft stools or an overall weakened immunity- they probably have unhealthy, imbalanced gut health. The most common and obvious signs of gut issues in dogs are vomiting, loose or semi-solid stools, increased frequency of bowel movement, flatulence, abdominal pain, weight loss, etc. Gastrointestinal issues in dogs can also affect behaviour by causing discomfort, leading to restlessness, irritability, lethargy, or changes in appetite and energy levels.
