I wondered about getting her a glucosamine supplement. Does it make a difference?
I was advised by my vet at the time to try it - but to find it cheaper than the vet could supply it (as they can only supply one tested on and warranted for dogs), which I did at my local chemist. The vet had said it could take up to 6 weeks to have any effect but I saw a big difference in less than a week. As Hopewell says, that could have been coincidence but I really don't think it was.
I also took Rimadyl from the vet, which she said to use if he was particularly sore any time, or if I knew we would be doing the sort of exercise that would make him sore. The combination of G/S and Rimadyl worked well for a good few years, keeping him comfortable and active.
WARNING - Rimadyl comes as a 'palatable for dogs' tablet which I discovered to my cost (and HOW) is also extremely palatable to - and dangerous for - cats.
Emergency nighttime trip to vet, plus all the care and treatments they gave him - £237. Ouch!
On the G/S or G/S plus chondroitin, I know a lot of people say G/S is pointless without chondroitin, but neither Horace nor I have had the 'with' version and both have found plain G/S helpful. At pretty high dose rates, mind.
Sorry about tangenting off topic, Tish - back to split ends, now!
