Bobke is a 4 year old DSH. Today I noticed his lips were wet. We couldn't see anything in his mouth so we figured he had just had a messy drink of water (not typical of him). He hasn't really acted like himself but nothing really obvious. Last night he slept with me which is unusual (too busy playing). He hasn't wanted to go out in the garage (closed and no chemicals he can get into). He sits by the door to go out there but changes his mind. He tried to jump up onto the TV and missed when he has done that many times without fail. I just noticed he's drooling. Not just the wet lips but a long shoelace of slobber. We looked into his mouth again and the tip of his tongue is red. Has anyone seen anything like this? I didn't notice anything different in our feeding ritual this morning but I'll make sure he's eating tonight.
