Alabama Rot in UK Dogs: What Every Owner Needs to Know

Alabama rot is one of the most feared canine diseases in the UK — rare, poorly understood, and often fatal. Since the first confirmed UK cases in 2012, hundreds of dogs have been affected, and the disease continues to be reported each year. Knowing the warning signs could save your dog's life.

What Is Alabama Rot?

Alabama rot, formally known as Cutaneous and Renal Glomerular Vasculopathy (CRGV), is a disease that damages the walls of small blood vessels in the skin and kidneys. It was first identified in greyhounds in Alabama, USA, in the 1980s, but the UK strain appears to be a different condition with an as-yet-unidentified cause.

The disease causes tiny blood clots to form within blood vessels, leading to tissue damage. In the skin, this manifests as sores or ulcers — usually on the paws, legs, or face. If the clotting affects the kidneys, it can trigger acute kidney failure, which is often fatal without intensive treatment.

Veterinary charity Anderson Moores, which maintains the UK's case database, has confirmed over 300 cases since 2012. The mortality rate for dogs that develop kidney failure is alarmingly high — approximately 90% of affected dogs do not survive once the kidneys are involved. Early identification and immediate veterinary attention are critical.

Researchers from the University of Surrey and other institutions have investigated possible causes including bacteria, toxins, and environmental triggers, but no definitive cause has been established as of 2026. This makes prevention difficult, though some patterns around season and environment have emerged.

Symptoms to Watch For

The earliest and most visible signs of Alabama rot are unexplained skin sores or lesions, typically appearing on the lower limbs, paws, or muzzle. These ulcers often look red, inflamed, or swollen and are not caused by any obvious injury. They can appear suddenly and may be mistaken for cuts or bites.

If the disease progresses to affect the kidneys, you may notice vomiting, lethargy, reduced or absent appetite, and dramatically reduced urination. These are signs of acute kidney failure and represent a veterinary emergency. The window between skin symptoms and kidney involvement can be as short as three days.

Not every unexplained skin sore is Alabama rot — many other conditions cause similar lesions. However, if your dog has been walking in muddy woodland areas (particularly between November and May) and develops unexplained sores, you should contact your vet promptly and mention the possibility of CRGV. Your vet can investigate further and monitor kidney function through blood tests.

Anderson Moores recommends washing your dog's paws and legs after every walk in wooded or muddy areas during the higher-risk months. While this has not been proven to prevent the disease, it is a reasonable precaution given the current evidence.

UK Hotspots and Seasonal Patterns

Alabama rot cases in the UK are not evenly distributed. The Anderson Moores case map shows clusters in areas including the New Forest, parts of the South West, Yorkshire, and Scotland, though cases have been reported across most regions of England, Wales, and Scotland. No area is entirely safe.

The disease shows a clear seasonal pattern, with the majority of cases occurring between November and May — the wetter, muddier months. This has led to speculation that a waterborne or soil-borne pathogen may be involved, but this remains unconfirmed. Cases drop significantly during dry summer months, which is reassuring for warmer periods.

All breeds can be affected, though certain larger breeds including Labradors, Golden Retrievers, Springer Spaniels, and Flatcoated Retrievers appear in the case data more frequently. This may reflect the types of dogs most commonly walked in woodland environments rather than a genuine breed predisposition.

If you live in or plan to visit a historically affected area during winter or spring, it is worth checking the Anderson Moores interactive case map online before your walk. Being aware of local cases helps you remain vigilant and seek veterinary advice quickly if your dog develops any unexplained skin lesions after a countryside walk.

Treatment and Costs

There is no specific treatment for Alabama rot. Management focuses on wound care for skin lesions and intensive supportive treatment if the kidneys are affected. Dogs with kidney involvement typically require hospitalisation, intravenous fluids, and sometimes plasma exchange therapy — a specialist procedure that carries significant costs.

Treatment at a specialist referral centre can cost several thousand pounds. Hospitalisation alone runs at £300–£1,500 per night, and intensive kidney management over multiple days can push total bills to £5,000–£10,000 or more. Pet insurance that covers hereditary and emergency conditions is strongly recommended for any dog that regularly walks in countryside environments.

Even with aggressive treatment, the prognosis for dogs with kidney failure is poor. However, dogs that are identified early — before kidney involvement — and receive prompt wound management have a better chance of recovery. This is why speed of action matters: if you see unexplained skin lesions, do not wait to see if they improve on their own.

Speak to your vet about any concerns. Given the severity of the condition, most vets will want to monitor kidney function even if the lesions look minor, particularly during the high-risk season.

How CompareMyVet Can Help

While Alabama rot cannot be prevented by comparing vet prices, being registered with a good local vet — one you trust and can reach quickly — is essential for any dog owner. In a suspected Alabama rot case, time is critical, and knowing exactly where to take your dog matters enormously.

CompareMyVet helps UK pet owners find and compare local vet practices at app.comparemyvet.uk. You can see consultation fees, opening hours, and whether practices offer emergency care or referral services. Being prepared before an emergency arises is far better than searching in a panic.

If your regular vet is closed, knowing your nearest emergency out-of-hours provider in advance could make all the difference. Use CompareMyVet to map out your local options today.
