How old is Merlin? My dog is very very old now and grumpy, but if I make eye contact her tail starts wagging, my dogs growing up, always wagging their tail. My parents dog, whole body jiggling with his tail wagging, but Merlin? Very very rarely wags his tail? That seems so strange to me? But maybe other dogs are like that? I’m when I’ve come across his sort of breed (not sure he isn’t mixed?) before they have always been quite jolly. Poor Merlin
