I have a 10 and a half year old Rottweiler and she was having some real difficulties getting around and in some severe pain. Thought we were going to have to put her down. Found your Liquid-Vet and started giving it to her. Within a week she was so much better. Now a month in she is acting like she is 5 again. I have recommended it to many of my friends with larger dogs and will continue to give it to my girl Karlie.
