I too am sorry for all that you are going through. I can't imagine.

I believe every pet that will not be bred should be s/n'd, this should be the default action. Don't keep him if you aren't planning to do this. The ASPCA should be able to do a much cheaper neuter. I'll repeat what everyone has said, please take him to a rescue if you don't keep him.

It sounds like maybe you need a sweet, older dog who can be more of a companion to you. Puppies, it's all about them. I agree with Archie, what you're describing doesn't sound that crazy, though it is possible he is picking up on the extreme stress you are under. For instance, on the leash - tons and tons of dogs bite the leash. You can just get one with a length of chain on the end, problem solved. Also, many dogs get walked with a harness, collar and leash, since a determined dog can slip out of its harness.
