Jonty and his stick

He's getting a bit funny about his Dentastix, sometimes he'll chew them up and sometimes not. Not sure if it's because he's got a touch of Gingivitis, haven't been to the vet but I think that's what it is. I've got some stuff from a veterinary on-line shop, must be good because it's expensive. Giving it to him daily so we'll see how it goes. Also brushing his teeth with a special toothpaste as he has plaque on his teeth. He's 13 and a half now and starting to show his age with little cysts appearing here and there so very careful when giving him a brush.
