Well, I'm not a breeder, but I know there is ALOT more work than, bring the dog over in heat and Tank and her can create whoopie and make baby bullies.
Granted the female bully gets the 'short end of the stick' with the surgery for C-section, risk of pregnancy etc.
Do you know that almost all bully breeding is done via artificial insemination? that means you will have to gather Tanks 'love seed' and there is a precise way to do it, store it, etc.
What do you know about Tanks breeding? how far back in lineage can you go? can you PROVE HEALTH ? Knees, Hips, allergies, etc etc, does he have any certificates for those area?
not to sound mean, but from your post it SEEMS like you see $$$$ or a Free Puppy from Breeding him breeding (I could be wrong, but this is how I read your post, as I didnt see anything about HEALTH mentioned or how to improve the QUALITY of the breed mentioned) if you intentions are true, to find a High Quality Female, (with Healthy certificates and championships and all of that history and paperwork of 'Quality') and if Tank is of the similar high quality, with everything to document) then maybe he would be good to breed to improve the bulldog breed itself. If not, and you mate him with an available female, then I anticipate those puppys will have a higher risk of ending up in a shelter, rescue or worse, due to health issues from Back Yard Breeding.
