Therapsida which began in this Moschops were put in reptiles just, but it showed an already mammalian shift type, and Kenodon appeared when they entered the (from 170,000,000 years to 200,000,000 years before) in a Triassic period, and Cynognathus did the form that seemed to remind you of a dog in particular and it depended and approached the mammals.
