I've read that Bouviers are considered "the old men of the dog world". My two, who went raw about 5 months ago are just shy of twelve and a half. My two are sisters and each went through their own detox with raw. They are definitely stronger and more agile now but their digestive tracts are not for the weak of heart. Can anyone tell me if this outrageous gas is a breed thing or should it improve with feeding raw?
