As a veterinarian, I have a soft spot for the Polish Lowland Sheepdog, or PON as many owners affectionately call it. These shaggy, sturdy herding dogs are bright, loyal, and remarkably long-lived for a medium-sized breed. In my exam room, they tend to be confident patients who watch everything I do with those wonderfully expressive, hair-covered eyes. Most of the PONs I see live full, healthy lives well into their teens, which is one of the joys of working with this breed.
That said, no breed is free of inherited risks, and the Polish Lowland Sheepdog has a handful of conditions worth knowing about before they become a problem. My goal here is not to alarm you but to help you spot the early signs and partner with your vet on prevention. Catching hip changes, thyroid shifts, or an early ear infection early almost always means a simpler, cheaper, and more comfortable outcome for your dog.
What Are the Common Health Problems in Polish Lowland Sheepdogs?
The Polish Lowland Sheepdog is a hardy working breed, but it carries a small cluster of inherited and breed-related conditions. None of these are guaranteed, and many can be screened for before you even bring a puppy home.
The most frequently discussed health concerns in this breed are hip dysplasia, inherited eye disease (including progressive retinal atrophy), hypothyroidism, and ear infections related to the heavy coat. Responsible breeding and routine vet care dramatically lower your dog’s lifetime risk for most of these.
Because the PON is a medium-sized breed with a deep working heritage, it does not suffer from the extreme structural problems seen in some giant or brachycephalic (flat-faced) breeds. Its build is balanced and athletic, which is good news for long-term joint and respiratory health.
Symptoms to Watch For
Many of these conditions develop gradually, so subtle changes are your earliest clue. I tell owners to trust their instincts. If something seems off, it usually is worth a phone call.
Sudden lameness, a painful or swollen joint, rapid vision loss, or an ear that is red, smelly, and clearly bothering your dog all warrant a same-week veterinary visit. Do not wait to see if these resolve on their own.
What Causes These Health Issues
Some of these conditions are inherited, some are influenced by lifestyle, and several are a mix of both. Understanding the source helps you focus your prevention efforts where they matter.
Inherited (genetic)
- Hip dysplasia (polygenic)
- Progressive retinal atrophy
- Inherited cataracts
- Some thyroid predisposition
Lifestyle and care
- Obesity worsening joint strain
- Neglected ear cleaning
- Matting that traps moisture
- Under-exercising or over-jumping young joints
Age-related
- Arthritis in senior dogs
- Age-onset cataracts
- Reduced thyroid function over time
Hip dysplasia, for example, is a malformation of the hip joint that has a strong hereditary component but is made worse by excess weight and high-impact activity in growing puppies. This is exactly why reputable breeders X-ray and certify their breeding dogs’ hips.
Treatment and Recovery
The encouraging news is that nearly all of these conditions are manageable, especially when caught early. Here is the general path I walk owners through once we have a diagnosis.
Get an accurate diagnosis
This may include X-rays for hips, blood tests for thyroid, or an exam by a veterinary ophthalmologist for the eyes. Treating the right problem is everything.
Address weight and nutrition
Keeping your PON lean takes pressure off arthritic joints and supports overall health. Your vet can set a target body condition score and feeding plan.
Use targeted medication
Hypothyroidism is controlled with a daily thyroid hormone tablet. Joint pain may be managed with prescribed anti-inflammatories and joint supplements your vet recommends.
Consider surgery when needed
Severe hip dysplasia or mature cataracts can sometimes be corrected surgically. Many dogs return to comfortable, active life after recovery.
Recheck on schedule
Chronic conditions need monitoring. Regular rechecks let your vet adjust doses and catch any progression before it becomes a setback.
Prevention and Home Care
You have more influence over your dog’s long-term health than you might think. Most of these steps are simple, daily habits.
- Buy from a breeder who screens hips and eyes on the parents
- Keep your dog at a lean, healthy weight throughout life
- Brush the coat several times a week to prevent mats and trapped moisture
- Check and gently clean the ears weekly, keeping them dry
- Provide regular low-impact exercise to keep joints and muscles strong
- Schedule annual wellness exams, twice yearly for seniors
- Watch for early changes in energy, vision, coat, and movement
- Ask your vet about senior blood panels as your dog ages
With sensible care, the Polish Lowland Sheepdog is one of the more durable medium breeds I work with, and most live happily into their teens. Knowing what to watch for simply means you and your vet can stay one step ahead.
Safety note: Any limping, vision change, persistent ear odor, or unexplained weight shift should be evaluated by your veterinarian rather than treated at home with over-the-counter products.

What you need to know
The Polish Lowland Sheepdog, or PON, is generally a healthy herding breed, though a few conditions appear in some lines. Hip dysplasia can lead to stiffness and an altered gait, while eye disorders such as progressive retinal atrophy may gradually reduce vision. The dense double coat hides skin and body condition well, so regular grooming doubles as a chance to feel for lumps or sore spots.
This is an intelligent, active dog that needs mental and physical work, and a bored PON can become restless rather than unwell, so it helps to rule out behaviour before assuming illness. Keep an eye out for night-time clumsiness, which can hint at early eye trouble. For any persistent limping, vision change, or skin problem hidden under the coat, a vet check is the safest next step.
