Irritating puppy!

I realise there's a swarm of photographic connoisseurs out there but fortunately not many of them follow my journal so the fact this blip is out of focus and actually rank rubbish may go unnoticed. 
Being Tuesday, it was my turn again to get children to music and swimming lessons - at one stage, I was able to sit down for a short break but then this! Not only did he undo my shoelaces, Paddy shredded the top of one of my socks. You'd think after 35 years of veterinary practice, I'd have wised up to delinquent puppy behaviour!
