How much Prednisone for 85 lb labrador?

Prednisone is prescribed to dogs for various reasons, and the reasons often determine the dose. However, as rule of thumb, the recommended dosages range from .1 to 3 mg per pound, up to three times a day. The lower dosages are usually given for anti-inflammatory reasons and the higher dosages to suppress immunity. The maximum dosage recommended for a 15 pound dog would be 45 mg, but is it best to check with your veterinarian before administering this or any drug.
