can’t see the point of designer mongrels myself. With a breed you have years of experience breeding for type and temperament (sometimes with downsides) so you know, within a normal distribution curve, what you’re getting. For example, the ‘merry cocker’, stubborn, trainable, unfailingly happy, smell and food oriented, crap ears, needs grooming, loves attention and people, likes the outdoors and comfort…with a cross you don’t know which characteristics of which breed you’re getting so it’s a lottery…
or get a mutt from a shelter…
