Do you have any holistic vets in your area? I too have fed raw for a few years and find what you are experiencing perplexing at best. I raise Saint Bernards so I don’t think I would be able to offer much insight for your particular breed. Sounds like you have tried going through the elimination process but just wondering do you feed the bones whole or grind them? I do both, some ground with their veggies and some fed whole, but just thinking maybe your little guy just needs the bones ground smaller. I wish I had an answer but encourage you to look for a holistic vet that may be more supportive as well as helpful when it comes to a raw diet.
