As far as I'm concerned, if I have another dog it will not be pedigree or a cross because mutts don't have so many issues
I’ve always had yorkies, the last one lived until nearly 20 and was a robust little dog.
I wonder if it’s because as show dogs it’s the coat that is the focus, the actual dog underneath hasn’t changed much from the ratters in the bradford mills. Excepting the ridiculous breeders of “teacups” and the like, which can’t be shown anyway because they don’t meet minimum size.
My mum has a cross, it’s always at the bloody vets. It’s got a congenital liver abnormality, and develops benign tumours which need removing.
I don’t think you can make statements about pedigree vs cross, as some crosses are unhealthy, as some pedigrees are. But there are pedigrees that have minimal health issues- poodles being one.
It’s about doing your research, questioning the breeder, whether pedigree or not, and making sure the dog you are buying comes from a quality source.
My current dog I tracked down through the pedigree of my last, so I knew the breeders and lines he, and his ancestors came from. I asked millions of questions and knew the type of yorkie I wanted.
