Sully's last blood work was less than a year ago. He has been on the Chinese herbs for about 1 month and they are Empirical Eye Support from PawHealer.com for his cataracts and Custom Hind Leg Weakness from the same company, for his hind legs. He drinks and urinates the same as before. Only, as soon as he gets up from sleeping (every time) he has to urinate.
The blindness is due to cataracts according to the vet and the weight loss was due (I think because he was only eating every other day) to the fact that he was eating dry food and the wet food was more interesting. He has eaten dry food his whole life and I knew that the wet food would get him to eating again and it did. He eats twice a day, about a third of a can each meal. His last blood work showed he was very healthy. It was only after his last good eye went completely blind that he stopped playing and started sleeping most of the day.
Thank you Candy for your reply. I do hope my vet has it. Sully is allergic to meat and can only have a special diet. So I will ask the vet if he has any of the products you mentioned.
