It is important to breed ‘like’ to ‘like’ as, you want to breed for certain traits that you want exhibited in your breed, but in the process of breeding closely relates dogs together, we also having those recessive traits come to the surface more. This is one of the most common causes of disease among purebred dogs. When you have dogs that are closely related, you are doubling up on genes too often and opening yourself up to more genetic disorders. Most disorders are a result of a recessive gene. It is important to understand how most genetic diseases work. Now, as for Elbow Dysplasia, Muscular Dystrophy, Degenerative Myelopathy, Ichthyosis, Patellar Luxation, Legge-Calve-Perthes, Dystrophic Epidermolysis Bullosa, Sensory Ataxic Neuropathy, Gangliosidosis, Osteochondrodysplasia and Von Willebrands Disease I and II, you will see the health benefits of this cross. This means that because they are common in both breeds, you will not get the beneficial effects of hybrid vigour with these diseases. So, Hip Dysplasia, Eye Disease, Heart Disease, Degenerative Myelopathy and PRA are all in common. Okay, now that we have looked at the common diseases amongst the two parent breeds, we can take a look at the ones that over lap. Hip Dysplasia (although not very common compared to Standard Poodles) Miniature Poodles struggle with the following diseases: Golden Retrievers struggle with the following diseases: How does this apply to Miniature Goldendoodles? Well, lets break this down. So essentially, hybrid vigour means that by crossing two unrelated animals to each other, you are decreasing the relatedness and therefore the overlap of genetic issues that are brought on by inbreeding and line breeding. Definition - is the improved or increased function of any biological quality in a hybrid offspring or the increased vigour or general health, resistance to disease, and other superior qualities that are often manifested in hybrid organisms, especially plants and animals.
