Outcrossing does not in any shape, form, or fashion guarantee a healthy litter. I can back that up with several breedings that were complete outcrosses for five generations and they had health problems. It all has to do with each dog in the pedigree and how sound it was, both mentally and physically. You also have no controll over type in outcross breedings, they may however still meet the standard. Outcrossing will add fresh genes to your breeding program and keep you from having genes depletion problems.
