We seem to have a preference for medium sized dogs. In my region, dogs are used for guarding purposes though they are good companions anytime. To this end larger dogs are preferred and we had one which was christened Simba for his size and valour in guarding the homestead at night. But I have recently developed a proclivity for small dogs which look exotic. I have also noted that small dogs are frequent feeders and are always foraging for edibles while large dogs have one large meal and spend most of their time lazing around though they are active at night. This has to do with their surface area to volume ratio and the need to conserve energy.
