Pet's info: Dog | Neapolitan Mastiff | Male | unneutered
I am thinking of adding a Neapolitan mastiff puppy to my family And I am thinking of giving him orijin puppy feed and some multi vitamin supplements and calcium supplement. Will excess calcium and vitamins affect his growth ? I want him to grow a little slow so that his bones will be stronger Or should, during growth period between 3 months to 6 months I will provide less protein puppy feed?
