[nagdu] Joint health.

[Deanna Lewis]

Hi,
My seven year old guide dog, Pascal has been slowing down over the last few months. The Vet also noticed some joint pain in his hips, low back and shoulders. I would like to start him on a joint supplement. I am considering Glucosamine and chondrointin. Is it safe to use human strength products, or should I purchase it from my Vet's office. How many miligrams does a 75lb. dog need? I was also told to put him on a fish oil supplement too, so what is a good amount of that to give him? What is the best way to give these supplements (do I put it in his food, etc)?
Thanks for any suggestions.
Deanna and Pascal
