The results of this study will surprise nobody who understands the basics of Mendelian inheritance. And without a doubt, mixed-breeds are sold at lower prices compared to purebred dogs. Some believe that there are many advantages to getting a mixed-breed for a pet, saying that a mixed-breed has a better disposition and can more easily adapt to its new home. VetCompass work will continue to help answer these vexing questions. No, mixed breed dogs are not ALWAYS healthier than purebreds and also, purebreds are not 'as healthy' as mixed breed dogs. There has been a longstanding argument amongst dog lovers and experts alike on the merits of a mixed-breed versus a purebred puppy. We have come a long way in the past few years and we now know which breeds live the longest and which breeds are most at risk for specific disorders However, we do not yet have an answer for which breeds are the healthiest overall. However, across many common and important disorders, breeds at high risk for one disorder are often at lower risk for another disorder ( Kearsley-Fleet et al 2013, Mattin et al 2014, O'Neill et al 2014, Mattin et al 2015, Summers et al 2015 ). On the question of the healthiest breeds, the lifespan of breeds varies widely, from 5.5 years in the Dogue de Bordeaux up to 14.2 years in the Miniature Poodle ( O'Neill et al 2013 ). So the answers are not that clear crossbred dogs do appear to benefit from a hybrid vigour effect for general characteristics such as longevity but seem to enjoy less advantage when it comes to the occurrence of specific common disorders. The main theory is that mixed-breed dogs have a greater genetic. With regular vet visits, careful selection of. Over the years, a general consensus has formed that mutts tend to be healthier than purebreds. In a study of more than twenty thousand dogs, a group of veterinary researchers studied factors impacting canine longevity at private American veterinary clinics. Comparing crossbred and purebred dogs, VetCompass studies show, on the one hand, that crossbreds live 1.2 years longer than purebreds ( O'Neill et al 2013) but, on the other hand, crossbred dogs have lower occurrences for only three from the top 20 disorders recorded in dogs ( O'Neill et al 2014). Mixed breed dogs are reported to live longer and stay healthier, but these are primarily anecdotal statements. No Difference in Lifespan Between Mixed Breed and Purebred Dogs. Although these might appear to be simple questions, VetCompass studies show that answers are not quite so easy. A current hot topic in canine health asks whether crossbred dogs are healthier than purebred dogs and which breeds are the healthiest. The VetCompass Programme uses clinical information on 2 million dogs shared from over 450 UK veterinary practices to examine health and welfare issues. So, are crossbred dogs healthier than purebred dogs?
