Almost any kibble or commercial dog diet in the long run would be healthier than only feeding chicken breast, I should think.
A healthy dog is exceedingly unlikely to starve itself long enough to do any harm. I suspect if they just stopped with the chicken and stuck to their guns the dog would start eating other food soon enough.
