Alabama rot: what dog owners should know

Alabama rot, known to vets as cutaneous and renal glomerular vasculopathy (CRGV), is a rare disease that damages blood vessels in the skin and sometimes the kidneys. Its cause is still unknown. It is worth knowing the signs without letting it put you off walks.

When and where

Cases have been reported across much of the UK, most often between November and May. Many affected dogs had been walked in muddy or wooded areas, though no single cause has been found.

What to look for

  • Skin sores, ulcers, redness or swelling that are not explained by an obvious injury.
  • These are most often on the lower legs and paws, but can appear on the face, mouth, belly or elsewhere.
  • In some dogs, kidney problems follow within days, with tiredness, vomiting, loss of appetite and changes in drinking or urination.

Keeping perspective

Alabama rot is rare, and most skin wounds in dogs are caused by everyday cuts, scrapes and infections. Even so, an unexplained sore is worth showing to your vet promptly, because early treatment gives affected dogs the best chance.

Sensible habits

There is no proven prevention, but many vets suggest washing off mud from legs and paws after walks and checking your dog’s skin regularly.

When to contact your vet

  • Any unexplained skin sore or swelling, especially on the legs or paws.
  • Tiredness, vomiting or reduced appetite in a dog with a skin sore.
