Some of these responses are batshit. A lab, for goodness sake?
Please don't get a poodle cross, OP. None of them are from reputable breeders and you'd be adding to the puppy farming issues that we have in the UK.
As for breeds, if you really like the CKCS, as long as you get one from a decent, reputable breeder who does all the necessary health tests, breeds to improve health, has good show results and endorses their puppies, then you shouldn't have any issues. Obviously get good insurance with any dog, as shit happens. They're lovely little dogs.
Other breeds that are relatively easy, small and non-shedding - Miniature or Toy Poodles. Really underrated, highly intelligent, fabulous little dogs with lovely personalities. Bichons are nice, but can be barky. Havanese are lovely. Mini Schnauzers if you can handle the barking. The issue is with non-shedding dogs is that they usually need professional grooming every 6-8 weeks, so budget for that. It's worth it, for the lack of hair, though. I have a perpetually moulting breed and am forever cleaning our the shower and washing machine filters, we go through hoovers like nobodies business, there is hair in and on everything despite constantly brushing, hoovering, cleaning, lint-rollering etc. It's an actual nightmare sometimes 😂
Also, be careful with Champdogs recommended above. Some of the breeders on there are puppy farmers. Completely avoid anyone who advertises on websites like Gumtree and Pets4Homes. The best breeders don't advertise their puppies.
