Can my aggressive older dog be trained to stop biting strangers?

My dog is six years old and he has always been aggressive with strangers. He has even bit someone years ago. We’re moving to another city soon and I would like to know if he could benefit from receiving any kind of training there.

The saying that old dogs can't learn new tricks is certainly not true. Dogs can benefit from training at any age and can learn new behaviors, so I think it would be a great idea to get some training for Rusty in your new city. Good luck! I hope that was helpful.
