The Majestic Tree Hound is a large to giant breed with males averaging over 100 pounds. They have the long, low-set earage (with a minimum length specified), heavy flew and dewlap of their ancestors from the Ardennes. They carry more excess skin in general than the American Blue Gascon, and are noteworthy for their abundant flew and dewlap, as well as facial wrinkles.

The Majestic Tree Hound is a good-natured and affectionate hound, accepting equally both praise and correction. It is not quarrelsome with other dogs and has a noble and dignified expression.
