As if we haven't got enough trouble, as it is. LOL. What passes as good in one decade, nay, one year, is no longer so the next.You'll get one breeder whose dogs are of a certain type, and favourable judges, and suddenly that's the way the winners have to be.If you want to start a lively discussion at Cruft's , find out what is 'in' and then mention it to those showing. A fair amount of heat will be generated and gossip reported!
Some of the changes in look may be generated by market forces. Who was it who decided that a golden retriever should be anything but golden?(Allegedly the Americans) The 'white' retriever would describe many better!
