I have know of dogs to eat grass to try and throw up and if you are saying she is constipated then she probably is doing the grass eating for this very reason.

She currently gets a handful of beef mince and half a can of my dog. And different doggy treats during the day.
Personally I would say that beef mince and my dog is a horrible diet as I feed a BARF diet.
For the constipation try a can of sardines or adding oil to her food.
If you must give her my dog I would be changing the beef mince to chicken necks three times a week, sardines once a week and lamb bones at least twice a week.
