Appreciate the info- thank you.
I'm giving Bogie (probably about 50 lbs) 1 1/2 grams Ester C twice a day as well as the glucosamin at the same time. I crush it and mix it in with yummy food.
Good luck. These old dogs are important to us. To show to what lengths we're going, we must go on a long trip to our grandson's wedding. We are taking our motor home instead of flying just so we can take Bogie with us. He's blind and we have no one that can take care of him.
