Dog World newspaper has gone into administration and has now ceased trading. http://www.dogworld.co.uk/

Haven’t take Dog World for many a year but I’m not surprised it is folding. A major part of the content was related to dog showing and there seems to be fewer people pursuing the hobby these days (at least that’s the case with my breed). Also, there are fewer pedigree dogs about - people seem to prefer cross breeds these days, even though they sometimes cost more.
