One of our dogs (Chow/St. Bernard mix) is about 11 years old and starting to have additional difficulties walking up stairs. As a result, we now take him up front to do his business but he hates not being in the pature with the other dogs and animals. To help alleviate discomfort we put him on a baby aspirin and glucosomine regimen. That seems to work most days but other days it takes him a bit to get up and about. We had someone recommend using Cetyl-M but we have zero experience with the stuff. Does anyone have a first hand opinion of Cetyl-M? Thanks!
