The Otterhound is a large, rough-coated hound with an imposing head. Originally bred for hunting, it has great strength and a strong body with long striding steps. This makes it able to perform prolonged hard work. Otterhounds generally weigh between 80 and 120 pounds (36 to 54 kg). They have extremely sensitive noses which make them inquisitive and perseverant in investigating scents. Consequently, they need particular supervision. They are friendly dogs with a unique bass voice which they use frequently.
The Otterhound is a bold and exuberant dog. Friendly, cheerful, loving and devoted, he makes a good companion. This breed is quite good with children, but may be clumsy with small children and therefore is not recommended for infants. They are a friend to all other dogs, family pets, children and people in general, however it will chase non-canine animals (it can get along with cats in the family). They are affectionate, intelligent. Because the Otterhound was never traditionally kept as a pet, it is not among the most responsive of breeds. Training the Otterhound takes patience. If the Otterhound senses the owners are weaker minded than himself it will become quite willful, acting independent with a mind of its own as they will believe they need to run the home. The best results are achieved with a determined, consistent, loving hand. Use the classic "Iron fist in a velvet glove" approach when training this dog. The Otterhound is a low-key dog that can function as a quiet companion. They like to roam and sniff and have a tendency to snore. Otterhound have a harmonious, boisterous and powerful voice that carries for long distances. It likes to bay; though he doesn't bark excessively.
The breed lives to between 10 and 13 years old, although some have reportedly lived to be 15 or older.
The Otterhound requires considerable exercise. They can be good family dogs but need to be kept in a secure property since they can jump fences up to 5 feet high.
