Your dog will be hospitalized and given supportive care. Oxygen may be given to assist in breathing, and intravenous fluids given to lower blood pressure. Anti-venom drugs are available and your veterinarian will administer them while monitoring carefully for reactions. The muscle spasms and severe pain will be controlled by intravenous administration of medications that will relax the muscles and bring relief from pain, allowing your dog to rest and recover from the spider poison.
Your veterinarian will want to monitor the wound site weekly until it has healed. The prognosis may be uncertain for days. Weakness, fatigue, and insomnia may persist for months.
