The way I understand it is that meat protein is a natural acidifier, so look for foods that are high in meat content. What some people do is add a half teaspoon of apple cider vinegar per cup of dog food, or give vit C or cranberry capsules. As long as your dog is full grown, I wouldn’t worry about large breed formula and if he isn’t full grown, you should know that a lot of large breed formulas are not actually appropriate for large breed puppies because they were not formulated according to the most up to date research.
