I do many things for my dog to gain his trust because I bought him from someone that basically abused him but he growls when I try to feed him and I'm trying to train him but he rarely pays attention(Well he never pays attention). What do i do?

Try clicker training. I just started doing it this afternoon with DANNI.  Basically we worked on "target" training.  We played a little game where I would hold my hand down near her.  If/when she came to sniff/touch my hand, I clicked the clicker and IMMEDIATELY gave her a treat.  After a couple of sessions of that game (about 10 minutes each time) we then worked with another dog.  Normally, when another dog comes near, DANNI growls and raises a fuss.  This afternoon, when we brought the other dog around, I would put my hand down and she would sniff my hand.  I then clicked and gave her a treat.  She totally ignored the other dog.

It was pretty miraculous.  Check out the link above (http://www.clickertraining.com) for more details.  I had never tried the clicker before, but I'm a believer now.

It sounds like the dog has some major issues and before he does much you need to get a handle on being the pack leader. Maybe you are feeling sorry for him? I know it's tempting to do that, but dogs see that as weakness, not as mothering. I suggest you seek out a behaviorist to get you started.

How old is this dog? Fixed yet? How are your walks? How do you feed him? You may need to start very slow, and hand/spoon feed the dog as a reward for sitting, responding to his name, etc, you have control over the food, if he growls, food goes away for a few mins, then you try again.. Don't just feed him because it is dinner time. Make sure he knows that you are "allowing" him to eat because you are in control, not because you feel bad.The mother has the say so over when pups eat/nurse, leader of pack eats 1st, then allows others. The dog needs to respect you, and obviously doesn't see you as an authority figure, therefore does as he pleases, not what is expected of him. Search for a good obedience club, and start building a "trusting" relationship, don't reward bad behavior. 

Take away the dog bowl.  I would hand feed your dog.
