I’m just going to add to your OCD, sorry. Hound Dog Mom has done a wonderful service for owners of large breed dogs and researched calcium levels on grain free foods. Your vizsla may or may not be considered a large breed because the breed is borderline with females usually smaller and males right at the weight to be considered large breed, so to be safe I would feed as if you know he is going to be large, which means watching calcium levels. Many foods that are labeled for large breeds still have calcium levels that are too high. Here is HDMs thread about large breed nutrition, in it is her list of foods with appropriate calcium levels:
