It's a supply and demand thing. Apparently prices doubled as the first lockdown was imminent, a lot if people were looking for companionship, a dog. Demand increases, .prices rise. .I can't understand why puppies are so expensive or is it just an English thing? When I was young, in the 50s and 60s, puppies were given away as no one in its right mind would even contemplate charging.
The world has certainly changed a lot and everything seem to have monetary value nowadays, sad I say.
