My puppy wont eat properly and he keeps going to sleep loads and then suddenly wakes up. He keeps jumping at the slightest noise, like when my mom opened the door to the washing mashine (which she does plenty of times everyday!) He jumped a mile!! He is being very snappy (which is not unusual but he's not normally this bad) he also has a runny tummy. And if this makes sence, i can tell he is not right :-(
He did nick a chicken wing, complete with bone the other night, could this be the cause

I really think you need to go to a vet, this may be why you've had so many temperament problems with him, maybe there's something going on here health wise.

Hope all goes OK.
