We recently got a puppy (13w female Aussie) and we noticed that whenever she goes on the grass it turns it yellow. I know this is common but I was wondering the safest and most effective way to prevent this. I have heard of chews you can give them but I am wondering if these are safe for puppies. My dog has had an upset stomach recently so if the best way is a chew or treat or something that she ingests I will be holding out for a little while until her stomach is feeling better. (And yes I am planning on taking her to the vet to see if it's just an upset stomach or something more serious) Thanks!
