OK so I know Roo is not even a year old, but I think I want to give him some kind of supplement. People do it a lot with horses and things like glucasamine, don't do any harm but prevention is better than cure surely, and so I don't want to wait until he is old and decrepid to give him something. What kind of thing would you advise? I don't plan to drug him up or anything but just give him a bit of something in his food a couple times a week for his joints or something? I know pedigree do joint care stuff, but pedigree have such a bad reputation in some respects, and they are very expensive... Any ideas/opinions?
