Personally I have nothing against the dogs,I have a major problem with those Breeders,breeding crossbreeds,sticking a high price on them and selling them with no health tests.
Some health problems are hereditary so will be passed on to the off spring regardless,this is why good breeders test for known conditions within there chosen breed,so they can breed the best two dogs,free from Hereditary conditions.
Another consideration is not all pups will be the same,they will take on different characteristics and traits,be completely different from one another in looks and personality.
We also have a major rescue crisis in the UK,with dogs been put on the PTS lists,because they don't have a secure rescue place,or a home.One dog is PTS every 80 minutes in the UK - These dogs didn't ask to be born either,we live in a very overpopuated dog world,so why deliberatly breed crossbreeds ?
