Overview

Repeated bacterial infections can reach the deeper skin layers and cause painful swelling, open sores and draining tracts. A severe recurring pattern was historically described in middle-aged German Shepherds and their crosses. Current veterinary guidance manages it like other deep skin infections. Finding an underlying trigger matters because an unresolved problem, such as allergic skin disease, can allow infection to return.

Signs to watch for

  • Painful, swollen areas of skin
  • Red bumps, crusts or patches of hair loss
  • Open sores or small openings that drain blood and pus
  • Similar skin problems returning after earlier treatment

The historically described German Shepherd pattern mainly affected middle-aged dogs.

When to get help Book a vet visit promptly for painful swelling, draining sores or another episode of skin infection.

Diagnosis and tests

Vets examine the lesions and check samples under a microscope to confirm bacterial infection. A bacterial culture and susceptibility testing help select effective treatment, especially when infection keeps returning. Further tests look for underlying problems, including allergies, skin mites or hormonal disease, that could explain the recurrences.
