Dogs aren’t known for their sophisticated palates. Their tendency to eat first and react later can easily backfire on them. So when dogs get sick and experience symptoms like diarrhea, nausea, vomiting or a loss of appetite it may be easy for a pet parent to think it was that stolen helping of birthday cake. But if these symptoms persist for weeks even intermittently in your dog they may be symptomatic of Inflammatory Bowel Disease (IBD), a chronic condition that occurs when the lining of the gastrointestinal tract becomes inflamed and loses its ability to properly digest and absorb nutrients. While the exact causes of IBD in dogs are not well defined and vary between individuals, Dawn Kingsbury, Chief Veterinary Officer at AnimalBiome, says there are several common factors at play among dogs with IBD.
