I'm certainly no expert but since I own one of each, I thought I'd tell you about my experience. My male definitely slobbers more than my female. It cracks me up, really. He'll drink some water then stand there with big strings of water/spit dripping from his jowls down to the floor! He looks so innocent, like "what is it Mom? Why are you laughing at me?" Absolutely adorable. I guess it's easy to see I'm boxer crazy if I think slobber is adorable!! LOL Not so funny on the chenille couches but, it doesn't bother me any!
