The Ultimate Mastiff in the Tundra variety. Created to be the ultimate snowy mountain and otherwise cold climate Mastiff. This one features the thicker, longer-medium coat. A tiny bit of French Bulldog lines were added to obtain the naturally upright ears. Moderate energy, calm around other dogs and family, can be aloof with strangers, never truly vicious. Tibetan, Spanish, Pyrenean, English and a little Neapolitan mastiffs make up the breed's genetics. #ultimate #mastiff #fictional #breed #dog
