My dog Shelby has occasional joint stiffness from years of playing really hard. As she’s gotten older, it’s become way too difficult for her to play frisbee or ball in the yard. We’ve tried similar pills & supplements, but she always refused to eat it unless I crushed & hid it in food or treats. We also never really saw any results from those products. I first saw this product at my local grocery store and figured I’d give it a try since it was liquid. Shelby really likes the flavor & always has no issues eating this with her food. Within about two weeks, I could also see more pep in her step, & we’ve again started playing some ball in the yard! She still has some rough days, but Liquid-Vet has been by far the best product we’ve used to date! When my first bottle ran out, I found out the store I was buying it at was featuring this product on a trial basis & there were no more in stock. Luckily, I had a business card for Jonathan, the owner of the company, & he personally returned my call to give me details on where I could find his products. Now that’s excellent customer service! I highly recommend this product!
