How should puppies be placed in cold weather?

It's normal for a puppy to urinate everywhere, so you can't leave it alone because you are afraid of getting dirty. Dogs are still young and cold in winter. It can't stay warm.

Solution to urinating everywhere: buy a dog toilet or make your own dog toilet. Use a bigger shoe box in the homemade dog toilet, not too deep, so that it can easily get in. Just lay a newspaper inside. Teaching dogs to excrete at designated points should be patient, not abusive, and only repeated education. Put a little bit of his urine in it, let him smell it, praise it if it is right, play for a while, point its nose if it is wrong, let him see how angry you are, and ignore it if you don't play. This process is very hard, I hope you don't give up.

Solution to keep your dog warm: buy a kennel or make it yourself. You can make a warm nest for him with thick cushions, old sweaters, etc.

In terms of food, we should pay attention to the hygiene of food and not give him leftovers. The puppy had better not let him eat cold food.

If all these can be done, observe for a few days and see if there are any other problems. Wish you success!
