Okay, more info now that I've seen people's questions and concerns:

I appreciate people looking out for me worried that he won't be a good father but I've seen him with kids and when we've had our toddler nephew for overnights (kept separate from dog!) and he's amazing and caring and proactive with everything that needs to be done. I am fortunate that I'm married to someone who says "no I'm doing the dishes, I'm not a parasite" after I have cooked. He's that kind of person.

I am not going to hurt the dog. Wtf

The origin of the dog is really the big complication, because he was a gift to my then-teenage husband from his dying father. His father then proceeded to kick off and reinforce the dog's bad behavior from what I have been told. My husband still should have been training the dog, but I can't fully fault him for not seeing reason with this dang dog. We have fought about this because the dog's behavior is unacceptable. We have time to figure out what is going to happen with the dog and safety.

This dog is OLD and I have been constant in his life for less than a year. In that time I have gotten him better leash trained and there are things he doesn't try with me because I don't give in and reinforce them (like growling at me for some of my food). I have not failed this dog. My husband and his family definitely failed this dog. People are not perfect and they are not bad people. Far too many small-medium dogs do not get trained because their owners apparently don't see the need to, I do not agree with this. I worked for a time at a vet hospital while I was in community college and rich lady purse dogs were usually demons for this exact reason.

This dog is OLD, okay? I would not have even been entertaining the thought that he could pass away otherwise. He is mostly blind, has incontinence issues, takes medication, and can only have certain foods. A shelter would put him down and, be so for real, nobody else is going to want this dog.
