So, I have a brindle pit bull. According to a doggy dna test, he is 91.4 % pure. I don't know if that has any legitimacy. Anyway, he is getting to be about 7 years old and I am curious as to the pros/cons of him breeding. I have an offer from a young lady in the neighborhood to possibly breed with her little pitty. Her girl is maybe 6 months old. I am not doing for financial gain. I just want him to be "fulfilled" before he gets too old. Also, I have read that breeding too young can be bad for the female. Is there anything unethical about anything I have mentioned? Are there any precautions I should know about?
