Is it normal for a dog to suddenly pee in its own nest?

It is an abnormal phenomenon that a dog suddenly urinates in its own nest. The reasons and solutions are as follows:

1. Maybe you are too timid to change the kennel, and the old kennel may smell of urine.

2. Dogs don't want to pee in their nests. If a three-year-old dog still urinates in his own nest, and always regards it as his own nest, the reason is that the method of training him to urinate is inappropriate, which makes him think that urinating is a prohibited bad behavior and can only urinate quietly in his own nest. You can always take it out, let it excrete as much as possible, encourage it when you find it excrete outside, don't beat it at home because of excretion problems, eliminate its fear and nervousness, and let it return to normal mental state.

3. You can go to a pet store to buy an inducer and let the dog urinate in a designated place.
