I have a 9 year old Springer Terrier and recently he has been experiencing some different behavior at night. When we go to bed he often makes strange noises like there's something stuck in his throat or mabey he's coughing? He also licks his nose & around his mouth a lot. It's like he's got peanut butter around the outside of his mouth but he don't. I always make sure he has fresh water right next to his bed but it dosent help. Any ideas?
