  • Diagnosis

    Clinical signs, genetic testing, and biopsy can be used to diagnose this condition.

  • Treatment

    Cracks in the foot pads make dogs more likely to contract a secondary bacterial infection, which can be managed with appropriate antibiotics; treatment of the foot pads with softening soaks can also reduce pain associated with the condition.

  • What to do if your dog is at risk

    Actions

    • Talk to your vet about your dog’s hereditary footpad hyperkeratosis result so you can plan appropriate care and monitoring.
    • Keep your dog’s paw pads moisturized and avoid rough or abrasive surfaces that could cause cracking or pain. Regular use of dog-safe paw balms or protective booties can help prevent irritation, especially during long walks or in extreme temperatures.
    • If you notice limping, bleeding, or signs of infection, contact your vet promptly for treatment and pain relief.
