I have a piece of constructive advice:
(1) Find a vet
(2) pay for a neuter for your boy & have operation done
(3) be happy with your healthy happy neutered boy
Frankly I don't even know why you would come on her gloating about doing such an insane breeding and then asking for advice with the resultant progeny
I can already foresee the future.....you are going to end up with an aggressive high drive dangerous puppy and then are going to come back here seeking advice on how to deal with her issues. Be responsible NOW and stop this problem from ever being born in the future.
However considering how well you seem to listen to advice posted, I doubt you'll neuter him nor be responsible about anything
