Have used this product for several years with several rescue Great Danes, Switched from Prozyme which is also a good product but Syner-G is not just a anti bloating supplement of course it eliminates gas but it also helps them increase the utilization rates of thier meals. Some of my rescues have been very thin and within 10 days of use the dogs literally bloom before your eyes. Great coats, great stools. Great Stuff ....:-)
I recommend this product to all dog owners & not just for senior dogs but for all ages. Our 13 Weim's coat is the skinniest & the her health has only improved. We have given Syner-G to all our dogs even the puppies, and with all the chewing, everything is "always digested ". Besides all the health benefits, it us an EXCELLENT value with the same ingredients as the more expensive brands.
