I use the following on my 2 year old Great Dane...she has HD, arthritis and growth problems in both her front legs!!!!
Glucosamine [high grade from the vets...payed for by insurance!!!]
Green Lipped Mussel [helps with cartlidge growth]
Devils claw [natural anti- inflamatory]
Omega 3,6,9 capsules
I get the last three from here.....

I use the Omega oils as I was offered a Hills food from the vet [can't remember the name of it], but is was �70 for 15kg and she would have needed approx 1kg per day [you do the maths.....lol. The vet gave a free bag and when I researched the ingredients the only thing of any value that I could see were the omega oils, so I just bought a supplement instead!
I started giving this combination six months or so ago and at the time she needed Metecam at least once a week....she hasn't limped or needed any pain relief in atleast 4 months.
Hope this helps
