Hello, I am afraid that the expert you have requested is not currently available. Still I am Dr. B, a licensed veterinarian and I would like to help you today.

In regards ***** ***** question, Bactracillin G can be given intramuscularly at a dose of 3,000 units per pound of body weight (1 mL per 100 lbs body weight). When treating, do so daily (usually for 2-3 days) and continue one day past full recovery. If the abscess doesn't settle or recurs, then we may need to lance it, sample the discharge for culture/sensitivity testing, and treat with an antibiotic that the bacteria is found vulnerable to on that testing.

Please take care,

Dr. B.
