There are a huge number of dog breeds around the world, and new breeds even keep appearing. But if there are indeed new breeds of dogs, there are others that have disappeared. There are various reasons for the disappearance of these races, but in the majority of cases, it is because these races were no longer useful to humans. So, here are 10 dog breeds that are now extinct.
10. The Alpine Mastiff
Having common ancestors with the Saint Bernard, the Alpine Mastiff is a breed originating from Switzerland. Even though the breed is now extinct, many physical and genetic aspects of the Alpine Mastiff can be seen in English Mastiffs. It is not known exactly when this breed became extinct, but it is believed to have become extinct in the 1800s due to extensive interbreeding with other dog breeds.
