Ive been thinking about this too.
I am the biggest animal lover there is....I would put him down.Something is wrong in his makeup and he is a danger to others.I wouldnt give him back at all.The dog is a serious risk to people,and if he harms a kid later you will never forgive yourself,even if he isnt a problem of 'yours' going forward.
The dog is just too high risk.
And yes I love boxers and pits,our dog park is filled with the nicest loving-est sweetheart pits you could ever meet,but a couple gangbanging jerks have brought some really horrible pits around that were just destroyed either by their environments or genetics that give them all a horrible name.
Had some jerk with TWO Boerbulls,that attacked everything thing in sight,he couldnt control them and says they are just playing.After the second incidence,first chased me up a bench,they were attacking a lab front and rear.
We called animal control,he smirks,its my word against yours.
Actually its not,told him in spicy language (and Mrs with her pepper spray and me holding a stun gun,have in car and seen him before) first bite is free,second is removal and death,and there is no fighting it either,its a done deal,they take dog bites real serious in Ca,and the animal control has big power here.He gets in his truck,sprays gravel over us and our cars,and never saw him again.
Now there is a guaranteed disaster that will happen in the future.
And its that kind of dog,and your experience that I urge you reconsider and put him down.
