I know nothing really about glucosamine supplements but I have a 2 year old mutt and her hips click when she sits and I have noticed she hesitates on the stairs. I spoke to the vet and he told me I can try glucosamine supplements.

The ones I started her on have 500mg glucosamine
400mg Chondrotin sulfate
50mg MSM
50mg Vitamin C
15mg Zinc
6 mg Hyaluronic acid
5mg maganese
2mg copper

That is per tablet and she is 40lbs and gets 1/2 tablet once daily.

Is this the recommended amount and if not what is..Thank you!
The name that i see on the bottle is 21st Century pet health.

She is also taking fish oil pills and co-Q10
