@SkiAndTravelTheWorldWithMyDog what do you mean?
Neither labradors nor poodles are brachycephalic so a labradoodle isn’t going to suffer from the breathing conditions associated with eg frenchies. Similarly ‘issues with their spines’ is a feature of breeds like dachshunds. Good breeders of those breeds will not breed from dogs with genetic faults like breathing problems or IVDD. That’s kind of the whole point about getting a pedigree dog. You can you find one with the relevant pre-breeding health investigations and you can see the genetic lineage for decades.
Personally I am not hung up on purebreds because I think the kennnel club is a horrible model and it has promoted breed standards that are unhealthy and damaging to dogs. However … they do maintain the only health test and genetic test database for dogs in England.
I’d never, not ever, ever, buy or rehome a dog without either: very extensive pre-breeding health screening of both parents including joint studies, heart scans, inbreeding calculations, and (very lastly) DNA profiles; or charity-covered vet bills.
Three friends got rescues. One Romanian: £13k in vet bills at 5 years of age for multiple joint issues; one Bosnian - brucellosis. It didn’t end well; another Romanian rescue with a serious allergy and treatments costing £170 per month. On and I forgot the lady across the road with a jack/ lab/ hound cross -she has been selling shit at car boot sales for the last 18 months to afford bilateral hip replacement for her dog -£17.5k.
Two friends got KC dogs. First got one off KC website - “health checks” - was a posh puppy farmer with several breeding bitches. Dog is reactive and really NOT a naturally reactive breed.
Second got a nice, healthy, trainable, amicable dog, super-rare breed.
