A dog with a human bite history and that does not readily get along with other animals as your adoption posting indicates is unsuitable for hunting or farm work.

It may be difficult to find a place for him because he has demonstrated that he is a risk and can pose a danger to others. You’re doing the ethical thing by not obscuring his bite record, but rescues sometimes will do so and it creates a lot more victims - sometimes even “dog laundering” to hide it (renaming and transferring the dog to another rescue out of state to hide the bite history). You need to give full details to an adopter/rescue about the bite, beyond what is in your adoption posting — do not sugarcoat it.

If you can’t find a rescue that will agree to accurately represent the dog’s bite history to potential adopters, you may need to seek behavioral euthanasia. The fact that the bite is bad enough to rehome indicates that it may be the right thing to do to consider this option, despite it being painful to think about. If a child was bitten, then you really should think all options through to determine what is the most ethical choice. While it is a sad situation to be in, you need to prioritize the safety of other people in this decision.

Edit: your comment responses indicate that your dog has a repeat bite history. It is extremely irresponsible to rehome your dog at this point because of this.
