Did you know the Catahoula Leopard Dog is one of the few breeds that are native to the United States? It originated in Louisiana and its history is quite unique. When settlers arrived in what is now the United States, the only domesticated animals they found were the dogs that belonged to Native Americans. When the Spanish explorer Hernando de Soto arrived in the 16th century, he brought his own war dogs, which began breeding with the native species. The result was the Catahoula Leopard Dog!
