Final answer:
The most effective immediate treatment for a bulldog's acute frostbite involves warming the frostbitten paws in warm water, avoiding direct heat, drying gently, and preventing infection with sterile bandages and potentially antibiotics and analgesics.
Step-by-step explanation:
The most effective treatment for a bulldog presenting with acute frostbite on his paws during the immediate, acute phase involves several steps. First, you should promptly warm the area by soaking the bulldog's paws in warm water, typically at a temperature of about 104 to 108 degrees Fahrenheit (40 to 42 degrees Celsius), for 15 to 30 minutes. It's important to avoid using direct heat, such as a hairdryer or heating pad, as this can cause further damage. After warming, dry the paws gently and avoid massaging or rubbing the frostbitten tissue to prevent further injury.
Protect the paws from infection by applying a sterile bandage and consider the administration of antibiotics and analgesics as prescribed by a veterinarian. It is also advisable to keep the dog hydrated and comfortable while avoiding re-freezing of the affected areas by keeping him in a warm environment. The bulldog should be taken to a veterinarian as soon as possible for further evaluation and treatment.
