Meat and any other foods

Can anybody tell me what is ok for dogs and what isn't please? Don't get me wrong but Nala tends to live on her three meals of dry food a day but for isntance the other day she had some chicken and rice whne she seemed to have a bit of an upset belly, but what about other meats? Is pork a no no? Also I looked into fruit and it said a little melon etc is fine - although thinks that are dairy based like ice cream are a no no. I'm not looking to give her things as meals but just the odd treat.
Thanks

Here's a link we've talked about before, may help

The only thing I can add to that is that pork is fine as long as it's fit for human consumption. The old myth was that it gives dogs worms, but nowadays pigs are wormed & the meat is checked before it goes on sale, so it'll be ok.
