Our sprocket is nearly 2. Yesterday my daughter had a friend round, our dog was asking to be stroked, the child did stroke the dog and then for seemingly no reason snapped at the child. It was a warning snap and really out of character so we wondered if the child had done something that we missed.
Today a different child round and again she stroked the dog- the dog had gone up and 'asked' to be petted and again for seemingly no reason he snapped. The children doing the stroking are teenagers so not little children and I've been in the room so know they weren't provoking the dog.
About 2 weeks ago he snapped at a man that was stroking him on a walk, we'd never met this man before and he was bending over the dog so we wondered is that was why. I'm now getting concerned that there is something else going on for a dog who had a fantastic temperament to suddenly start snapping 😞
