Yes lol, dozers tongue always hangs out. He has a genetic defect in his jaw. It didn't show up until he was 5 months old, and went through a growth spurt. His jaw grew longer than it should be, and when the vet checked him, we discovered that he is also congenitally missing two of his bottom molars. This causes him not to be able to close his mouth completely because his top and bottom jaws don't meet. It doesn't affect him in any way other than he eats a little slower than his sister, and we add warm water to his kibble to make it a little softer for him to chew, and his tongue always either sticks out like he's sticking his tongue out at you, or it hangs out to the side, and oh yeah he drools a little more than his sister too, because his mouth is open. Lol, and he gets a dry tongue sometimes, so we always have water available for him. Dozer eats, sleeps and plays with his tongue out. Lol. You can see from his picture of the side view how his jaw is longer than it should be, and you can see his picture as a puppy with his sister when we picked them up from the breeder, he didn't have that. We love him the way he is though, it gives him character, and his face always brings a smile to my face. He's our Dozey.
