Thanks all :) I am mighty proud parent. Drool in Tosas vary quite a bit. I'd say my male drools the most, usually really gluey stuff that hangs in slingers from the corners of his mouth. My older female is next up, she's like a leaky faucet when she's about to get food, blows bubbles and all out her lips. The other two really don't drool. I do have to wipe mouths after eating and drinking, but it's not bad other than that. They're house dogs, and once a week i do a wall inspection and clean up any slingers that they've shaken off. Generally, the bigger the jowls (loose lower lip), the worse the drool.
