This video is absolutely hilarious! This situation is very much applicable to humans too. Let us explain. You know that there are two types of men, the ones who want attract the person they like by writing poems, songs, playing instruments, singing and the ones who are persistent and simply ask directly for what they want. Although the former might be more romantic, in most cases the latter ones are more successful. While the romantic ones are performing their Peacock tricks, the other ones are taking all the girls, or boys if they are so inclined.
This video is very much the same! While one dog is trying to perform a trick to impress the owner, and earn a treat, the other dog just comes and takes it! The lesson of the story? If you want something, take it as quickly as you can!
