Have used their sprinkle supplement for my dachshunds..oldest is 12 yrs., for over 3 years now. My pets are spry like 2 yr. olds!! I love their green lipped mussel!! Sure I could find it cheaper...but the quality wouldn't be the same...and my babies deserve the BEST!! ..and no..I'm not a paid customer or given freebies..I pay for every package I get!! I did my research before I chose Ace-Canine.
