The worst thing about this entire thing is lots of people aren't even buying puppies from reputable breeders...they're buying puppy mill puppies.
Lots of KC breeders didn't breed from March-onwards of last year BECAUSE of lock-down. Some of the dog breeds are actually in danger because breeders couldn't breed (such as the Dandy Dinmont who already had low puppy numbers anyway...).
Anyone who bought a puppy in lockdown should be ashamed of themselves (if not pre-planned). Even if you WFH full time, if it's in a stressful job, you probably can't give the puppy the attention it needs.
In normal times breeders should be inspecting homes and/or vetting people before they sell dogs to them. The KC breeder we got our spaniels (brother and sister, same litter) from asked for photographs of our garden with one of us in the photo (as proof), she made sure someone would be home nearly all the time (dad retired so all fine) and she asked to do a 2 month inspection. She even highlighted the risks of getting spaniels (exercise needs, cancer, eye diseases etc) and discussed insurance prices with my parents so they were aware how expensive it could be...All things breeders should do. The fact she was so thorough was incredibly reassuring. We made sure we saw both parents with the puppies/each other, ensured the puppies were health tested and visited them at 3 times before we purchased them.
As many posters have said the price of puppies also shot up in lockdown (which reputable breeders don't do...) so people are paying £2-3K for dogs that have questionable origins and health.
People who shouldn't own pets was a huge issue Pre-COVID and this has just compounded it.
Breeders and buyers need to be far more responsible.
