Are you aware that once a male dog starts breeding he will lose his close bond with you and be much more interested in “other things”? Think of an 8-year-old boy vs. an 18-year-old boy. Also, unneutered male dogs are much more likely to get hit by cars in their search for “other things”. There is also a greater risk of cancer in unneutered male dog. So if you really love Buddy maybe you could look into cloning.
