After doing a lot of research on senior dig vitamins I decided to get these for my 16 year old Lhasa Apso. She doesn't really have joint problems yet but had lost a lot of her energy and just slept. This is month 2 of these senior vitamins and she is doing great. She has a bit more spunk and her KCS has improved (with vitamins and her other eye treatments). I have read that people complain about the size. They are easy to break in half and my toothless dog doesn't have any problems taking them. Great price, too!
My pets seem to be having a taste issue with it. I crush it up& mix it with their wet food. I have noticed a change in agility & energy.
