Hi
I dont know if this is what you want to hear but if he was mine i would have him put to sleep.
if he got someone on the street he would be in BIG trouble.
I do feel very strongly about temprement in any dog but certainly rotties.
His is ok with the other members of the family?
Is he is any pain or ill ?
Is there a reason he bites you,though not acceptable especially as you have needed surgery.
It is a hard decsion to haver him put to sleep but please dont pass on a dog with this temprement,you can never be truly sure that he is happy and being looked after.`
