How vets diagnose it

Full-body examination after clipping fleece.

Treatment

Call your vet; control bleeding with pressure; keep the alpaca calm and warm. Antibiotics and tetanus prophylaxis are usually needed.

Do not wait to see if it improves. Camelids hide illness, and by the time signs are obvious the problem is often advanced. Call your veterinarian.

  • Livestock guardian dogs or llamas
  • Lock animals in at night in high-predator areas
