Should I stop?

[Bobbymutt(Kids100)]

Ok, currently my dog's getting stomache pains. He's throwing up, using the bathroom more often, and eating grass a lot. We don't know why. We don't give him food that might be too bad for him. BUT he doesn't like Dog Kibbles sooo...we sorta spoil him. Warm toast with Peanut Butter for breakfast, Grilled Cheese Sandwich for Lunch (Sometimes) or some of my Leftovers and He licks the plates after everyone's done eating, and sometimes Chicken soup for Dinner or Left overs and plate duties. Should I stop giving him these foods and make him eat his? Will it hurt his feelings? I don't want him hurt.

Another thing, He's aggressive. Why? We got him as 11 months old. June 15th 2007. His Birthday is July 4 2006. When we got him his first owners were African Americans and they kept him in a small apartment with a lot of kids who tortured him. That was only his first few months of life. Around 7 months old. They gave him away to these people who onl wanted Chihuahuas. So Bobby was nice with Chihuahuas, as he grew up nicly with them. Sadly they didn't give him much attention. He wasn't aloud inside, only the Chis were. Then they gave him to us. We took him home, excited that he gets to meet our very old dog. When we brought Bobby he went into a Tantrum trying to Kill my Honey Boy. H snapped, growled, and barked at Honey. My old GSd couldn't move good and was deaf. He could only watch, hoping Bobby didn't get him, cuz He was 16 and would make it if Bobby attacked him. So Bobby had to be tied up away from honey. Upsatirs. Honey wouldn't climb up there. He couldn't even make one stair. After a month of trainig with Bobby they were able to be together. Bobby no longer needed to be tied up, but I took him for a walk when a JRT was lose, Bobby went into his tantrum and pulled me to it. Bobby is now MUCH bigger and stronger thn last month. I let go and..it wasn't pretty. Me and my nieghbors threw hard toys at the dogs to get them away from each other. It worked after a while. No dogs were harnmed. Bobby was meaner after that though. He got aggressive towards any humans to. He's very protectiv eof me especially. And if he saw the chance he'd run off take a wlak around the neighborhood and cause troule...bad trouble. So I teached him to come when called and to stay. So I can have him outside withou a leash, finnaly. But I have to be careful cuz anyone or dog can pop up from anywhere. What can I do???

Yes, I'd advise having him eat his own food. My dog used to be picky too. To make him eat it, you just have to lay down the law. Lay down his food for 15 minutes, and if he doesn't eat it, put it up until the next day and don't give him anything else to eat that day. After a few days of this, at most, he should start eating his food. He will not allow himself to starve unless possibly he is ill.

As for aggression, sounds like lack of socialzation is his problem. You can have him gradually introduced to other dogs from a distance. When he's fine with that, you can eventually get closer. Take it in steps. Wait until he's perfectly calm at a certain distance before trying any closer. Use high-value (treats he absolutely loves) treats (or toys, if he's not a treat kind of guy) to reward him for good, calm behavior.
If he slips up, go back to the last step that worked. And when he gets to where he can stand calmly right next to a dog, keep a close eye on him, and be ready to jerk him back if needed. Until you can trust him completely.

Do not try this all in one day. This can take weeks, even months. But it's more than worth it.

The Dog agrresion I don't think I can fix. I think MAYBE he's part Pittie. But I dunno. He has the Pittie Chest, Muzzle, Smile, Behavior. Here's a pic of Bobby, a good pic. It shows his Qualities good:

He is a beauty. If he has any Pit Bull, it's probably very little. I see more of the stockier-type Lab features than anything. Maybe a bit of Great Dane too. The box-y head and muscular neck, chest, etc are features found in several breeds.

Most dogs can be rehabilitated from aggression, it just takes time, consistency, and patience. Michael Vick's dogs were rehabilitated, some even becoming therapy dogs. Only one, according to my sources, had to actually be put down.
