Why do dogs stick when they mate? In this new video from AnimalWised we will answer this question and explain in a clear and simple way why dogs get locked together after mating. If you have ever witnessed this situation or simply would like to know the reason for behavior, discover with us why dogs get stuck when they mate, something that happens during the canine copulation process. This mating process is required for the different stages of insemination to occur. We also show you why it is so important not to separate dogs which are stuck during mating. If you want to know a little more, you can go over to our site to read the original article: https://www.animalwised.com/why-do-dogs-get-stuck-when-mating-the-answer-2432.html

Male birds have the largest genital diversity of any class of animals because their sex chromosomes make it easy to pass male-helping mutations down the line.
