I am planning to adopt a golden retriever puupy in few months time. I started to think about where he should stay at night. Ideally, I would like him to stay in his outdoor dog house (in the garden) at night - we are in a quiet area, no neighbours and well fenced garden.

However, I am not sure when I should introduce the puppy to his outdoor house? I do not think it will do any good for the puppy to let him stay whole night outside in the first few days (even weeks). He would probably quite nervous when he first arrive to his new home . Any suggestions and recommendations are welcome.

Thank you!
