The reasons why dogs howl like wolves in the middle of the night:

1. The ancestors of dogs are wolves, so sometimes they imitate wolf howls.

2. When a dog is in estrus, it will secrete some hormones that it does not normally have, which makes it very excited and imitates howling like a wolf.

3. The dog discovered danger and wanted to alert its owner.

4. When the dog has not seen its owner for a long time, the dog will miss the owner very much and its bark may sound like a wolf.

5. Some dogs will vent their boredom by imitating wolf howls.

Tip:

If you don’t want your dog to imitate howling like a wolf, you can call your dog over to appease it, or you can train your dog not to bark at ordinary times, and you can pair it with some snacks during training.
