My 12 week old puppy has settled in well and sleeps all night until about 8 am. The problem is that when he does wake up and after he has been fed , he goes nuts for about an hour or longer. I appreciate he's had a lot of rest and has energy to burn but he just won't leave me alone. He's constantly pawing at me and biting. I try and give him some attention and do a bit of training with him but the pawing, if I take my eyes off him and try and drink some coffee , is relentless. My legs are full of scratches. Its difficult to get dressed and tidy up let alone eat some breakfast. No amount of chews or toys will distract him. Has anyone any suggestions or will he just grow out if it?
