Well, my old lab got struvite crystals in his bladder and went through the internet for answers. Long story short, he lost the crystals and was ph balanced until he did reach his end of life 3 months later, but he died of old age, the blood labs went to very normal! Now that my other two, Candi the hound and Uzi my B are still on raw since Oct 2013, I am assured they area totally healthy. For the Basenji, that they do not drink so much, he gets liquid via the raw food, and he looks sooooo good! I love it that he does not have to poop so often and all his chemistry labs always come back 'perfect'. I don't have any fears about later I life either. Protein and the variety he gets is doing the job. Kibble needs so much water to break down. Now, there are many that are excellent, but I just can never go back to it…..
