Hidden Giant Dog Breeds Known for Loyalty and Calm Temperament
Here we go, one by one.
1. Otterhound
The Otterhound is one of the rarest dogs you will ever meet, yet it has a warm personality that quickly wins hearts. This big dog breed was originally bred in medieval England to track and hunt otters through rivers and streams.

Despite its hardworking past, the Otterhound is a true gentle giant with an incredibly gentle nature. It enjoys spending time with its family, develops a strong emotional bond, and often responds well to human emotions.
According to PetMD, the Otterhound has a kind temperament, making it an excellent family dog. Although this large breed has a natural protective instinct, early proper training helps it grow into a confident, well-mannered companion.
