My son bought that rock bag last year and didnāt see any big difference. Now he has 3 dogs lol. I always have a beautiful green grass as I trained all my dogs to go in the back in their pooping pen. But this Duke seems to forget at times. Itās really his first year n I canāt complain. Winter just finished n I do have a few spots to fix plus frozen ice will burn grass to. Nyala goes on her own in the back n I would say Duke 60%. But thatās Duke. Oddly he poops in back but for pee, he will pee here and there. Why I make a point to go outside with him each time. Little sh*t just pee on my new egg bbq.
These rock are really sulfur rocks. Dogās urine is high in nitrogen, reason why your grass gets yellow spots. Iāve seen n heard of ppl changing their dogās food or give tomato juice to help balance the dogās ph. Sorry but I rather play around with my grass than my dogās diet cause i wanna nice grass. I donāt think the rock bag is a bad thing but does it work 100%? Idk. Down the road, I find itās easier to train the dog n fix your own grass.
