While a Peke is the one breed I will NEVER have (see below), and I am more likely to adopt (which isn’t free BTW) than buy from a breeder, I see no reason not to go to the next step and ask the breeder a bunch of questions. Just don’t get drawn in by puppy cuteness, and be prepared to back off if you encounter red flags.
They say we don’t remember things that happened before we are about 5, but I have several strong memories from before we left England, when I was 2 1/2. One of the strongest was when one of my grandmother’s Pekingese tried to bite me when I was passing something (I think it was a cigarette lighter) from my mother to my grandmother. I don’t think she actually broke the skin, but I was terrified.
Meena, my grandmother, was Freud-trained psychoanalyst, and a dog breeder. She showed first Samoyeds, and then Pekingese, at Crufts. I learned to walk by holding onto Wolf, a Samoyed which Meena had given to my parents for a wedding gift, but I never got over being attacked by that Peke.
About 10 years later, in the US, Meena lived about 60 miles away from us, in a small house with 20+ Pekingese. None were house trained or neutered, as that would “damage their psyches”. They also had many eye injuries. Meena had no sense of smell (my father attested to that from his childhood, when he was told to eat rancid butter because Meena thought it was perfectly good.) In the US she never cleaned up after the dogs. She just put down newspapers, and then covered up the feces with more newspaper, and so on, until it was a veritable Napoleon. My mother and I could stay in the house for a maximum of 5 minutes before we had to leave. My father and sister wouldn’t go in the house at all.
So I can’t see a Pekinese without a visceral memory of the fear of being bitten, and the smell of well aged dog feces.
