As a veterinarian, I have a soft spot for the Sussex Spaniel. They are one of the rarer spaniel breeds, with that distinctive rich golden-liver coat, a low and rolling gait, and a calm, affectionate temperament that makes them wonderful family companions. Owners often come to me delighted by how mellow and devoted these dogs are compared to the busier sporting spaniels. They are genuinely lovely dogs to live with.
That said, every breed carries its own pattern of health concerns, and the Sussex Spaniel is no exception. Because the breeding population is small, certain inherited conditions appear more often than they would in a larger gene pool. The good news is that most of these issues are either preventable, manageable, or screenable before you ever bring a puppy home. In this guide I will walk you through the conditions I watch for most closely in this breed, the early signs to recognize, and what you can do to keep your dog comfortable for as long as possible.
What Are the Common Sussex Spaniel Health Problems?
Sussex Spaniels are generally robust, but the breed is predisposed to a small cluster of conditions: hip dysplasia, chronic ear infections, intervertebral disc disease (IVDD) related to their long-backed build, certain eye problems, and a rare inherited metabolic disorder called PDP1 deficiency. None of these affects every dog, and many are caught early with routine care.
The Sussex Spaniel is a low, long-bodied, heavy-boned dog. That distinctive build is part of what gives them their charm, but it also shapes their health risks. A long spine and short legs put extra demand on the back and joints. Long, pendulous ears trap moisture. And because the breed nearly disappeared after World War II and was rebuilt from a very small number of dogs, the gene pool is narrow, which concentrates a few inherited conditions.
None of this should scare you off the breed. Plenty of Sussex Spaniels live full, comfortable lives into their early teens. The key is knowing what to watch for so you can partner with your vet early rather than reacting to a crisis.
Symptoms to Watch For
The earlier you notice a change, the more options we have to help. Here are the signs I tell Sussex Spaniel owners to keep an eye on.
Sudden hind-leg weakness, dragging of the back legs, or an inability to stand can indicate a disc problem and should be treated as an urgent issue. Likewise, repeated collapse or fainting during exercise needs same-day veterinary attention.
What Causes These Conditions
Most Sussex Spaniel health problems trace back to genetics, their physical build, or lifestyle factors like weight. Here is how the main causes group together.
Inherited Genetics
- Hip dysplasia (polygenic)
- PDP1 deficiency (single-gene, DNA testable)
- Certain inherited eye conditions
- Narrow gene pool concentrating risk
Body Structure
- Long spine prone to disc disease
- Heavy bone stressing joints
- Low-set, pendulous ears trapping moisture
- Deep facial folds near the eyes
Lifestyle Factors
- Excess body weight straining hips and back
- Infrequent ear cleaning
- High-impact jumping on the spine
- Skipped routine wellness exams
Genetics set the stage, but daily care often decides whether a predisposition becomes a real problem. A lean Sussex Spaniel with clean, dry ears and a sensible exercise routine sidesteps a surprising amount of trouble.
Treatment and Recovery
Treatment depends entirely on the condition, so this is always a conversation with your own vet. That said, here is the general path of care I follow for the issues this breed faces most.
Get an Accurate Diagnosis
Many signs overlap. Your vet will use a physical exam, X-rays, ear cytology, or DNA testing to pinpoint exactly what is going on before treating.
Treat Ear Infections Fully
This usually means medicated ear drops and a thorough cleaning. Finish the full course even if the ear looks better early, or the infection often returns.
Manage Joint and Back Issues
Mild hip dysplasia and IVDD are often managed with weight control, controlled rest, pain relief, and physiotherapy. Severe cases may need surgical referral.
Support Metabolic Conditions
Dogs with PDP1 deficiency need lifelong management guided by your vet, with careful attention to diet and exercise limits to avoid collapse episodes.
Schedule Ongoing Monitoring
Chronic conditions need rechecks. Regular weigh-ins, joint assessments, and ear checks keep small flare-ups from becoming emergencies.
Recovery timelines vary widely. An uncomplicated ear infection clears in a couple of weeks, while a disc injury may need weeks of strict rest. Follow your vet’s recheck schedule rather than guessing from how your dog looks day to day.
Prevention and Home Care
You cannot rewrite your dog’s genes, but you can shift the odds heavily in their favor with consistent home care.
- Keep your Sussex Spaniel lean, since extra weight strains hips and the spine
- Clean and dry the ears regularly, especially after swimming or bathing
- Discourage repeated jumping on and off furniture to protect the back
- Provide steady, moderate daily exercise rather than weekend overexertion
- Feed a complete, balanced diet appropriate for your dog’s age and size
- Buy only from breeders who screen for hips, eyes, and PDP1
- Keep up with annual wellness exams and senior bloodwork after age seven
- Watch for early signs and call your vet sooner rather than later
When to See Your Vet
Some changes can wait for a routine appointment, while others need prompt attention. If your dog suddenly cannot use its back legs, collapses during exercise, or shows severe pain, treat it as urgent. For gradual stiffness, recurring ear trouble, mild eye changes, or unexplained weight gain, book a visit soon rather than waiting to see if it passes. When in doubt, a quick call to your veterinary clinic is always worth it. They would rather hear from you early than late.

What you need to know
The Sussex Spaniel is a low, sturdy gundog with a few breed-specific concerns. Its long, heavy ears trap moisture and are prone to infections, so check and gently clean them weekly and dry them after swimming or wet walks. The breed can carry an inherited heart defect called pulmonic stenosis, and intervertebral disc problems are a risk given the long back and short legs, so discourage repeated jumping on and off furniture.
Hip dysplasia and ear-related deafness in some lines also appear. Sussex Spaniels gain weight easily, which strains the back and joints, so portion control matters. Eye conditions can develop with age. Because this is a rarer breed, a vet familiar with spaniels is helpful. For any ear odour, back stiffness or breathing concern, seek veterinary advice rather than treating at home.
