Yes wolfsoul you are right.
I will never give my dogs the supplements they make for this problem because of the ballder/urinary/kidney problems that can occur. I did check w/ my vet & they say tomato juice is not AS bad as the supplements but it DOES still change the acidic levels in the urine, therefore I will NOT give that to my dogs either!
I'll just stick to looking at some yellow spots & keep watering the grass.
