We have urban dogs and the worst thing are the foxes. They jump - over a six foot brick wall - and go to our rubbish stall. The girls go bollistic - even if we are all asleep with doors and windows shut. I am always in two minds to let them out and chase them away or try to calm the baying and instinct down as the London foxes are becoming more and more fearless and aggressive. We have a fortunate and so maybe not position being between two big parks so we get quite a lot of urban wildlife - my favourite was when ducks landed in our little pool....
