A long-backed herder carries a long-backed risk
The Cardigan Welsh Corgi is a sturdy, long-bodied herding dog on short legs, and that shape explains much of its health list. The breed is most often linked with intervertebral disc disease, because a long spine supported by short limbs puts extra strain on the discs between the vertebrae. Hip dysplasia also appears, along with progressive retinal atrophy, an inherited eye condition that gradually affects vision, and degenerative myelopathy, a spinal condition seen more often in older Cardigans. Weight gain deserves its own mention, because extra pounds load both the back and the hips of a dog already built close to the ground.
None of this means a Cardigan will develop these problems. It means an owner who knows the pattern can watch the right places, keep the dog lean, and bring useful observations to the vet rather than waiting for a small change to become a crisis.
Back trouble is the watch that matters most
Disc disease in a Cardigan can show first as reluctance rather than drama. A dog who once hopped onto a low step may pause, yelp when picked up under the chest, walk with a hunched back, or go quiet and stop herding the household around the kitchen. Back legs can look wobbly or drag slightly in more serious episodes.
Help the spine in everyday ways. Keep jumping off sofas and beds to a minimum, use ramps or steps where this dog regularly climbs, and support both the chest and the rear when you lift a Cardigan instead of scooping under the middle. Sudden inability to use the back legs, crying out in pain, or loss of bladder control is an emergency that needs a vet the same day, not rest and waiting at home.
Hips, eyes and an ageing spinal cord
Hip dysplasia in this breed may appear as stiffness after rest, a swaying or bunny-hopping gait when trotting, or reluctance on longer walks that a younger Cardigan handled easily.
Progressive retinal atrophy tends to affect night vision first, so note if your Cardigan hesitates in a dim hallway, misjudges a step at dusk, or becomes cautious in unfamiliar dark places. Degenerative myelopathy, by contrast, often starts in an older dog as painless hind-leg scuffing and wobbliness that slowly progresses, which is one reason any hind-end change in a senior Cardigan deserves a proper work-up rather than an assumption about old age.
Keeping a Cardigan lean is preventive medicine
Cardigans were built to work all day on modest rations, and a house dog can gain weight quietly under that thick double coat. Feel for ribs regularly with flat hands — you should find them under a thin covering, not hunt for them, and not feel them sharp and bare. A visible tuck from the side and a waist from above matter more for this breed than a number on a chart, because every extra pound is carried on a long back.
Ask the vet to score body condition at each visit and to note weight in the record, so a slow creep upward shows as a trend instead of a surprise.
Questions worth taking to your Cardigan's vet
Ask whether your dog's parents had hip, eye and spinal screening, whether a baseline eye examination makes sense, and how often weight and gait should be rechecked as your Cardigan moves into middle age. Bring dates and short notes: when the hesitation on steps began, whether it follows exercise, and whether it is better in the morning or evening.
KinsLe's Pet Passport keeps a Cardigan's screening results, vet notes, weight history and eye checks together in one portable packet, so the back, hip and vision story is complete at every visit, not scattered across old paperwork.
