OMG yaass!!! Pick a popular breed because they're easier to take care of instead of those pesky obscure ones that may need extra attention!!!
Sometimes, relatively unknown breeds can be popular over a particular geographic area. For example, there is the Carolina dog, which is related to the dingo, the Indian pariah dog, the chihuahua, the Mexican and Peruvian hairless, and probably others that are not coming immediately to mind.
The official breeding group is actually relatively narrow, but their native range is actually in the southeastern United States. If you look around for dogs that are up for adoption, you can find many dogs that are quite obviously, if not Carolina dogs, at least Carolina dog mix. However, if you lived wayyyy over in California, far away from the native range of the Carolina dog, and got a purebred from someone that breeds them, then that dog is really coming from an extraordinarily narrow breeding population.
In one geographic area, you can't avoid them, which is really good news for protective genetic diversity, but in the other, the population is so small that you are going to run into potential genetic bottlenecks that could result in major genetic problems that lead to an uncomfortable and unpleasant existence for the dog.
The Carolina dog is therefore an example of one breed that many people do not really even know about, but they are abundant in certain areas. Many people even outright deny that dogs existed in the United States before the Europeans came: the narrative some people believe is that there was nothing but wolves and coyotes, here, and "white man" came and released their dogs to run amok and destroy native habitats. They are genuinely uncomprehending of the fact that the Americas have always had indigenous landrace breeds. Unfortunately, it has been only recently that more Southerners have been taking more pride in their native wildlife, so in spite of these "yellow dogs" being a famous symbol of the region, it is only recently that we have been acknowledging that these dogs are an indigenous part of our fauna that is unique to our region. Old Yeller acted like a wild animal because Old Yeller actually WAS a wild animal. They have been a part of our way of life for so long, we just never thought about how they got there. They run loose because they are wild animals, and they are therefore SUPPOSED to run loose.
However, the right place for the dog is in an area where that particular breed has already been proved to be both successful and popular.
There might be reasons why that dog is popular there. In the case of the Carolina dog, they are specially adapted for the unique climate and geography of the southeastern United States in ways that other breeds or even coyotes and wolves are not. It's a wet climate, down here, with lots of thick vines and briars that would lead to torn, matted, and unruly coats in many breeds. They are popular precisely because they are uniquely adapted for the area, and they have been successful as a landrace breed.
Essentially, I was not saying that it is bad to want an unusual breed, and in fact, there could be many highly unusual, unique breeds that have uncommonly high breeding populations in your specific area, possibly for very good reasons that are unique to the strengths and adaptations of that particular breed.
