I have been an advocate of yours for a pretty long time. Financial difficulties prohibited me from buying your product for my 3 pups. You were always at the top of my list for things "needed" once I had some extra income. Going without your vitamins for 2 months, I worried but didn't think anything of it. Well, I finally had the $$ to purchase another bottle and may I say, I will NEVER go without your product again. My dogs' energy perked up, they're happier and they absolutely LOVE the words "you want your vitamin"? Thank you thank you thank you. It's quite obvious your product is all and more than you warrant. Thanks for giving me my puppers back, even the older 9 year old rat terrier!
