From Kate MacDonald, South Uist, Western Isles, UK
I was horrified by the image that you used to illustrate your piece on the workings of a dog's mind (7 April, p 12). The dog pictured is brachycephalic: it has been bred for an exaggeratedly broad, short skull with bulging eyes.
Such dogs may suffer all their lives from serious respiratory difficulties. Many also experience painful eye conditions.
