“Works great for my English Lab, she is 14 years old, she has been taking it for 2 years. Dog is required to get blood work every 6 months, to ensure she is still able to take this med. I am very happy, that this product helps her.”
“My 16 yr old Lab, sheppard, hound, yes, hound..112 lbs of her, does wonderful on Norvox and this site has the least expensive I have seen so far. I don't know about the service yet as I just ordered today. Let you know when it comes how it went.”
