When my dog was a puppy it was discovered that she has Irritable Bowel Syndrome (yes dogs can get it too). It didn't matter what food I fed her...she had tummy problems. She couldn't keep any food in except for the extremely expensive prescription food that the vet prescribed, and I subsequently had to buy from their office. I then discovered Solid Gold Barking At The Moon dog food. The dog trainer recommeded trying a gluten-free food. I tried it and wow! My dog was easily able to tolerate it. Her tummy problems disappeared (along with a strict diet excluding people food). The food is also all-natural which I love. My dog is like one of my children, so it's important for me to feed her a high-quality food. It's more expensive than other grocery store dog foods, but you feed less of it because it's a higher quality food with no fillers. You can't buy it in a grocery store either. I've only found it in pet stores excluding the big chain pet stores. Still it's worth a little bit of a drive and a little bit more money to relieve my dog's discomfort.
