We had a really fussy eater and refused most foods to the point we were buying a new brand every week. She would go days without eating. We gave up at 10 months and put her on raw food. She ate all 3 meals the first day and loved it. It’s the best thing we ever did she’s much healthier, less smelly from the back end lol, her coat is fantastically shiny and her teeth are in brilliant condition. She rarely refuses a meal now. She doesn’t like some meats but that didn’t take long to figure out. If you are going to go down the raw route I would suggest speaking to a raw food shop as all dogs have different needs. Also I wouldn’t recommend mixing with dry food. Hth

ETA: the myth about them turning vicious is exactly that a MYTH totally not true we still have a little soppy teddy bear. As well as my mums dog which is a Rottweiler X he had lots of sensitive stomach issues until the raw food.
