Question: does apple cider vinegar help with dog urine?
Answer: You will sometimes hear that it is the acidic pH of the dog's urine that kills the grass and that you should feed your dog tomato juice or cider vinegar to adjust the pH of the urine. Don't do it! Turf grasses actually prefer a slightly acidic pH, but can tolerate a wide range – 5.5 to 7.5 or higher and still do well.
