Two of my dogs have had urine tests that came back with high ph, and my vet said that she actually sees that often with dogs who are on grain-free kibble and suggested a diet change. These two dogs are eating approximately 50% Fromm Lamb and Lentil kibble, 25% Honest Kitchen Embark, and 25% random things I add in - the usual stuff like raw eggs, yogurt, meat scraps etc.
They are also eating copious amounts of pears and cherries from the yard, and I found those two fruits in a list of foods that make urine alkaline. is it possible that eating tons of pears and cherries is changing their PH that much?
I know that I should be eliminating kibble from their diet entirely, and I will if I have to but it's hard to stretch the budget any further with 5 dogs. If it's just the pears and cherries I know things will be back to normal soon - or at least until the figs come in.
