So Buddy's urinalysis showed he is on the too acidic side contributing to the calcium oxalate crystals in his urine. I got these test strips to see if his diet change is making his urine more alkaline. They work pretty good and it only takes a minute to see the result. It comes with a color chart to compare the strip to. My last Basenjis had their urine too alkaline which resulted in bladder infections. I got this on Amazon.
