A good starting dose of prednisone for an average size mouse (25-30 grams) is 1-2 mg/kg once daily. This dose can be increased or decreased as needed, based on the mouse's response to the medication. Prednisone should be given orally, either in tablet form or mixed with water.
It is important to note that prednisone can have side effects, including weight gain, increased thirst and urination, and decreased activity. Long-term use of prednisone can also lead to more serious side effects, such as stomach ulcers, Cushing's syndrome, and diabetes. Therefore, it is important to use prednisone only when necessary and to monitor the mouse for any side effects.
If you are considering using prednisone to treat your mouse's respiratory issues, it is important to talk to your veterinarian first. Your veterinarian can help you determine the appropriate dosage and duration of treatment for your mouse.
