If he does it a lot I would take him to the vet. If he only does it on occasion and it's mostly when he is excited or just drank water I wouldn't worry. Georgie does it as well and it seems very common. I blow at Georgie's face (well his nose) to get him to stop. That works well. I watched the video and can totally relate to it Georgie does the same thing and I was so worried. Thank God for YT
