I have a 4yr old Lab who suddenly exibited the same behavior last night. Jumped out of bed and started licking floors, walls, windows! After a trip outside he came in and drank alot of water. Last week he had 2 nights of a kind of cough after lying flat in bed. He is also on Wellness Dry but its "Super5Mix". Im not feeling comfortable with the Wellness brand coming up so often in this post. Im hoping its just a coincidence. Anyone have any thoughts? Vet says heart is strong, may be an upper resp. infection and gave him meds. Other than this strange behavior, everything is completely normal with him.View Thread
