All dogs have 2 coats. Their coat will be the normal hair you see and then a fine fur under it. If you push their fur backwards and lift up a bit their should be a finer fur.
The fine fur, the undercoat is thinner in the summer and thicker in the winter, how thick should depend on the amount of time they get to spend outside and how cold it is where you live. That breed would have less of an undercoat in FL, thicker in NY.
