Sussex Spaniel Weight & Calorie Guide

Sussex Spaniels are the heaviest of the spaniel breeds, originating from Sussex, England, where they were developed to hunt in dense undergrowth. Weighing 35–50 lbs on a relatively short-legged frame, they are compact, muscular, and notably melodic — known for their distinctive baying voice while hunting. Their heavy build on short legs creates significant joint stress, predisposing them to hip dysplasia, intervertebral disc disease (IVDD), and otitis externa. Every extra pound increases spinal compression and hip deterioration in this already heavy-set breed.

Exercise: Sussex Spaniels need 40–60 minutes of daily exercise. They are methodical, ground-scenting hunters that enjoy long sniffy walks through fields and woodlands. They are not built for sprinting — their short-legged, heavy-body conformation means low-impact, sustained activity is ideal. Swimming is an excellent option that builds fitness without joint strain. Regular ear cleaning is essential to prevent chronic infections.

Feeding tips: Feed two measured meals daily using a quality formula for medium breeds. Sussex Spaniels are prone to obesity — their stocky build makes owners underestimate weight gain. Strictly measure portions and avoid table scraps. Limit treats and use part of the daily kibble allowance as training rewards. Consider a joint supplement with glucosamine after consulting your veterinarian.

Keeping your Sussex Spaniel at a healthy 35–50 lbs (16–23 kg) is critical for spinal and hip health. Use PawScale's calorie calculator for Sussex Spaniels to control portions, check body condition with our BCS assessment tool, and build a balanced meal plan with the feeding guide.
