To answer your question
wtf have I done
bought a puppy from a backyard breeder that has probably spent its first 16 weeks with its mum and not much human contact - to them it’s a commodity not a dog
Decided after 2 1/2 weeks that was not the best idea
not considered it might cost more than you think
I’ve got a puppy the same age. Mines a rescue a probably had an equally sad start - she was dumped 3 weeks ago
The difference is I’ve been fostering dogs for years so i accept that a puppy like this is going to be a long term project and expecting much more than that in 2/12 weeks is a lot.
It’s a baby. It’s a breed that is a one person dog. It had a poor start tk life. Go back to basics and treat it like it’s a 8 -10 week old puppy (which mentally and development wise may be) and don’t t expect a fully formed pet because of its age.
if I’m a bit short, well you did ask and as a foster I pick up the pieces of people who have buyers regret of live animals.
give the poor thing a break - build up leaving slowly and gently, but do just walk out, no fuss no drama.
my puppy is a bit Velcro at the moment. She’ll be fine.
