Watched some videos online of dogs in the street spending days pursuing a female in heat. There's always two pitbulls/rottweilers fighting for the top spot, some medium-sized mongrels hanging around to snag the female when the alphas are not looking, and finally waddling in between the legs of the others are the doglets like chuihuahua mixes and other rat-looking mixed-breeds.
The doglets look outright comical next to the other superior dogs and not only do they stand absolutely no chance of getting the female who is usually ten times bigger than them, but they also get kicked around like little soccer balls by the larger breeds. Found it a little funny until I realized that that's what us manlets must look like next to the average human being.
