The newly bought 40-day-old golden retriever always sleeps during the day and purrs at night. Why? How to solve it?

It's absolutely easy to train, but almost all puppies do. Puppies sleep as much as babies, and their bladders are underdeveloped, so it is impossible for them to endure urine like big dogs. The best way to train their BB is to be locked in a small space, which must be his safety zone. The so-called safety zone means that they will never shit in this place (dogs actually love cleanliness and don't like to shit next to their nests). It's a little troublesome for puppies ~ 3 times a day ~ 8 am, 5 pm and before going to bed at night, every time after feeding 10 minutes. As the dog grows up (after three months), it can be shortened to twice. Sooner or later, you will find that the puppy itself is very reluctant to urinate at home during the fixed-point stool training.
