The reason why the dog is always straddling the kennel recently is because the dog is in heat. Usually dogs become sexually mature when they are 6-7 months old, and then they will show signs of estrus. Male dogs may mount some objects after they are in estrus. The owner can take the dog with him at this time. Get spayed or neutered so your dog won't behave like this again.

Tip:

It is not recommended to mate when a dog is in heat at 6-7 months old, because the dog’s reproductive organs have not yet developed. Perfect, mating and breeding will cause great harm to the body and may even lead to death, so it is best to breed the dog after the dog reaches adulthood at 12 months.
