Matty is also known as Max, Muddy, Mutz and stubborn.

Being a teacher's dog, he not only has to greet everyone who enters his home, which is normal for this breed, but he also has the added responsibility of assisting his master with the grading of papers. It's not easy for him to hold the marking pen in his fuzzy paw, but he tries his best.

Making circles and large yellow spots on less than stellar test papers is his favorite thing.
