Wisconsin’s State Dog — and One of America’s Rarest Breeds
Only a few hundred American Water Spaniels are registered each year, making the AWS one of the rarest AKC breeds despite being one of the few dog breeds developed entirely in the United States. Bred specifically in the Great Lakes region for waterfowl hunting from small boats in cold water, they are medium-sized, curly-coated, and versatile.
That small gene pool matters. With lifespans of 10-14 years, the AWS carries elevated risk for hip dysplasia, cardiac disease (particularly mitral valve disease in older dogs), and epilepsy. Health testing of all breeding stock is especially critical for a breed with this few registered individuals — every litter affects the gene pool more than it would in a common breed.
Key Health Challenges
Hip Dysplasia: The Primary Orthopedic Concern
Hip dysplasia is documented in American Water Spaniels. OFA hip evaluation at 24 months is recommended for all breeding stock. For a hunting dog, hip joint integrity directly affects working life and enjoyment.
Lean body condition and controlled exercise during skeletal development reduce clinical expression.
See the Hip Dysplasia guide for full prevention and management detail.
Mitral Valve Disease: Start Listening at Age 5
Mitral valve disease occurs in American Water Spaniels, typically developing in middle-aged to older dogs. Annual cardiac auscultation by a veterinarian identifies the characteristic murmur before clinical signs develop.
When MVD is diagnosed, echocardiographic staging determines when cardioprotective medication should begin, following the EPIC trial protocol. The window between murmur detection and symptom onset is your opportunity for intervention.
See the Mitral Valve Disease guide for full prevention and management detail.
Epilepsy: Above-Average Rates, Usually Manageable
Epilepsy occurs at above-average rates in the breed. Idiopathic epilepsy most commonly presents between ages 1-5. Two or more unprovoked seizures warrant a full diagnostic workup.
Management with phenobarbital or potassium bromide controls seizures effectively in most dogs. Drug level monitoring every 6 months maintains therapeutic efficacy while minimizing side effects.
See the Epilepsy guide for full prevention and management detail.
Science-Backed Longevity Strategies
After Every Swim, Dry the Ears
American Water Spaniels were bred for cold-water waterfowl retrieval and retain strong swimming instinct. Their floppy ears trap moisture after swimming, creating prime conditions for otitis externa. Weekly ear inspection and drying after water exposure prevents chronic ear disease.
Dogs used for regular hunting or water work should have ears cleaned with an appropriate ear-drying solution after every swim session. This is a 5-minute routine that prevents weeks of treatment.
The Coat Repels More Than Water
The AWS double coat is oily and water-resistant — a working trait that has practical implications for parasite prevention. Topical flea and tick products applied to the skin may not absorb effectively through the oily coat. Oral or systemic parasite prevention is preferred for this breed.
The curly outer coat needs brushing every 1-2 weeks to prevent matting, with periodic professional trimming. Avoid bathing too frequently — monthly or after heavy field work is sufficient. Over-bathing strips the protective oils that make this coat functional.
Why Health Testing Matters More in a Rare Breed
With only a few hundred dogs registered annually, the American Water Spaniel’s gene pool is small. Comprehensive health testing of all breeding stock is not just recommended — it is important for the breed’s long-term genetic health. Prospective owners should seek breeders who test for hip dysplasia, cardiac disease, and epilepsy family history. The American Water Spaniel Field Association maintains health resources and breeder referrals.
Priority Actions for a Longer Life
The prevention priorities with the best evidence behind them for American Water Spaniel owners:
- OFA hip evaluation at 24 months — hip dysplasia documented in the breed
- Annual cardiac auscultation from age 5 — mitral valve disease develops in middle-aged and senior dogs
- Dental care from puppyhood — small-to-medium spaniels have elevated dental disease risk
Make these the backbone of your American Water Spaniel’s preventive care calendar. Each quarter, assess whether you are on track or need to escalate. Detailed protocols live in Hip Dysplasia, Mitral Valve Disease, Seizures Epilepsy .
Evidence-Based Longevity Priorities
Body Composition Predicts Long-Term Function
Body composition control predicts long-term function more reliably than most other single factors in American Water Spaniels. As a medium breed, body composition stability directly predicts orthopedic longevity and cardiovascular reserve. These dogs were bred for endurance work and maintain better muscle quality when activity patterns remain consistent.
Prevention Stack for the Top Three Risks
Your highest-yield prevention effort targets Hip Dysplasia, Mitral Valve Disease, Seizures Epilepsy. Early, consistent action on these conditions preserves the interventions that late detection forecloses.
Stable Routines Protect Cognitive and Physical Health
Inconsistent exercise schedules often show up first as behavior changes, sleep fragmentation, or slower recovery from exertion in American Water Spaniels. Stable routines protect both cognitive function and physical resilience.
Screen Before It Compounds
Proactive screening on a set schedule catches subtle drift long before a crisis-driven vet visit would. The dogs who do best are the ones whose owners detect changes while they are still early and reversible.

What Genetic Testing Can and Cannot Tell You
For American Water Spaniels, genetic testing delivers the most value when results directly change what gets measured, how often, and what triggers escalation. Consider hip and elbow scoring (OFA or PennHIP) to quantify orthopedic risk. In a breed with this small a gene pool, testing is not just about your dog — it contributes to breed-wide health data.
- Run a genetic panel that targets the conditions most common in American Water Spaniels. Treat the results as a monitoring guide, not a diagnosis — confirm findings through serial clinical follow-up.
- Your first monitoring protocols should target Hip Dysplasia and Mitral Valve Disease. The goal is results that change behavior — not just data that sits in a file.
- Create a health timeline that follows your American Water Spaniel across life stages. Include test results, clinical findings, medications, and home observations — it turns isolated data points into a readable trajectory.
- Genetic results mean different things at different ages. What looked like a low-risk finding at two years old may deserve closer monitoring by age seven when the clinical picture has changed.
The point of testing is not the result — it is what you do differently because of it.
Built for Cold Water and Small Boats
The American Water Spaniel was bred for stamina, retrieval work, and sustained field activity in the cold waters and marshes of the Great Lakes. That heritage created a versatile, weather-resistant hunter with orthopedic demands that follow from a lifetime of active retrieval work.
- Prioritize surveillance around Hip Dysplasia, Mitral Valve Disease, Seizures Epilepsy.
- The difference between catching a problem early and catching it late is often just paying attention to the small stuff that repeats. One off day is nothing. Three in a month is a trend.
- Lock in a regular cadence for reviewing your monitoring plan — at minimum every three to four months. What you should be watching for at five years old is different from what mattered at two.
Breed heritage sets the surveillance priorities. Your American Water Spaniel’s individual data tells you when to act.
When to Screen, Test, and Reassess
- Puppy to 2 years: OFA hip evaluation, CAER exam, ear care protocol established
- 3-5 years: annual cardiac auscultation begins, wellness bloodwork every 2 years
- 6+ years: senior panel annually, cardiac monitoring, dental care, mobility assessment
What and How to Feed
American Water Spaniels do well on quality medium-breed adult food sized to activity level. Working dogs used for hunting need higher caloric density than companion dogs. Lean body condition throughout life supports both joint health and cardiac function.
Omega-3 supplementation supports coat, skin, and joint health. Avoid bathing-stripping shampoos — use gentle, coat-protective formulas that preserve the natural oils.
The Healthspan Horizon
American Water Spaniels with proactive cardiac monitoring, orthopedic screening, and appropriate water-work management can live healthy active lives reaching 13-14 years. Their versatile hunting heritage supports robust general health when workload and recovery are well-balanced. For a rare breed with a small gene pool, each well-managed dog contributes to the breed’s future.
The Subtle Signs You Are Most Likely to Miss
Healthspan erosion in American Water Spaniels typically begins with subtle shifts that are easy to overlook:
- Subtle hind-limb stiffness after rest related to Hip Dysplasia — dismissed as slow mornings
- Exercise intolerance or a soft cough after exertion that hints at early Mitral Valve Disease progression
- Brief staring episodes, confusion, or transient disorientation that may signal early Seizures Epilepsy
If baseline function is drifting for 7-10 days, treat it as a prevention failure signal and reassess early.
