    Methio Firm

    By Jilly on Nov 10, 2020

    It’s been 9 months since I’ve been able to order the methio form tablets for my dog who makes crystals in her urinary tract.....please get this back in stock as I believe she is starting to have problems again. What has been the problem in not stocking this until December when I requested it in January 2020????

    Urine acidifier

    By Hildy818 on Oct 8, 2019

    This has helped my dog maintain the correct urine PH so that she does not get crystals, cystitis or infections. I am so grateful to my Vet for suggesting this product. It's too bad that it is so difficult to get. I've had to order another brand that is not laced with liver and so I must crush it in her food. I prefer this brand as it serves as a 'treat'. What do we owners/consumers have to do to get Lloyd to keep it in stock?????
