Best Supplement for s Senior Dog

My dog is 9 years old and I want to put him on a good supplement. He is not having any issues and most of the supplements are for joint health. Are there any just good all round senior ones?

Smartpak has a good mutivitamin for Seniors. Saw a nice improvement in my elderly dog.

This isn’t an all-round supplement, but it’s made a big difference in the elderly dog I adopted.

She’s anywhere from 14-16 yrs. old and has become so much more active and perkier. With a good diet she’s become young again. She has some signs of early dementia so I’m starting Senilife tonight; I expect an even more noticeable change in the weeks to come.

Actiflex really helps my 14 year old. I can tell a difference if we miss more than a dose or two.
