Help Me Housebreak My Westie And Get Her To Stop Urinating When Greeting People?

I have a westie, she is 7 months old. I have had her 5 months. I have tried crate training and she would pee and poop where she sleeps and eats–she eats her poop. I clean her mess and tell her bad girl – you should go outside (she knows what outside means). She doesn’t go in the same spot – she goes where it hits her.
I have 4 dogs and she is the only one under 30 lb., my other dogs were housebroken before they were 5 months old. Is training small dogs different? She is not dumb. I have taken her to the vet there is nothing medically wrong with her. I do believe that she came from a puppy mill and had to eliminate where she slept and ate. I had been Adolph’s meat tenderizer on her food and she stopped eating her poop – but seems to have started again. After working with my vet and going through the ID diet, I feed her Nature’s Recipe Lamb and Rice puppy food.
I love my puppy but NEED HELP WITH HER HOUSEBREAKING AND URINATING WHEN SHE GREETING PEOPLE. HELP HELP HELP !
