Otterhound Breed Profile & Growth Guide

Breed Overview

The Otterhound is a rare and distinctive scent hound that originated in medieval England, developed specifically for hunting otters in rivers and streams. With their dense, water-resistant double coat, large webbed feet, and remarkable stamina, Otterhounds are perfectly adapted to work in wet environments. They are friendly, affectionate, and intelligent, with a deep, melodious voice and a strong sense of smell that can track scents even in water.

As a breed, Otterhounds are sociable and good-natured, making them excellent companions for active households. However, their independent nature and powerful nose mean recall training can be challenging.

Size Category: Large
Adult Otterhounds typically weigh 80–115 lbs for males and 70–100 lbs for females. Growth tracking is particularly important for this breed due to their size and predisposition to joint problems such as hip and elbow dysplasia. Monitoring growth helps ensure steady development and prevents excessive weight gain that can strain their joints.

Gender Differences:
Males generally weigh 5–15 lbs more than females and tend to have a more robust build.

How Much Bigger Will My Otterhound Puppy Get?

Most Otterhounds reach about 50% of their adult weight by 5–6 months. They achieve most of their height by around 12 months but will continue to fill out in muscle and chest depth until 18–24 months.

Rule of Thumb:
A reliable estimate for adult size is to double your puppy’s weight at 16 weeks.

Note:
As a large breed, Otterhounds benefit from controlled growth. Rapid weight gain can increase the risk of joint problems later in life.

Otterhound Growth Tips

Nutrition

• Feed a high-quality large-breed puppy formula to support steady bone growth and avoid excess calories.
• Maintain a two- to three-meal feeding schedule until 6 months old, then transition to two meals per day.
• Avoid overfeeding and excessive treats to prevent obesity.

Exercise

• Provide moderate, low-impact activity such as leash walks, gentle play, and supervised swimming.
• Avoid strenuous jumping, running on hard surfaces, or stair climbing until growth plates close at around 18 months.
• Engage their mind with scent games and tracking exercises.

Health Watch

Otterhounds may be prone to:

• Hip and elbow dysplasia—monitor weight carefully during growth.
• Bloat (gastric torsion)—feed smaller, more frequent meals and avoid vigorous activity after eating.
• Ear infections—their floppy, water-loving ears need regular checks and cleaning.
