Hello, JACustomer. I have been a Veterinary Nurse for over 15 years and would be happy to help you today. I'm reviewing your question right now.

Expert:  PitRottMommy replied 2 months ago.

How much does Corbin weigh? How many milligrams is the penicillin you have? In what form is it?

Customer: replied 2 months ago.
150lbs 60 ml of 300,000 units per ml. Pro pen g, injection
Expert:  PitRottMommy replied 2 months ago.

The dosage is available here: http://www.canine-epilepsy.com/docs/Medication-Conversion-Pets_Penn-126-TheDogPlace.org1.pdf

1mL/30# ***** SQ every 48 hours. This would be 5mL per dosing for a dog his size.

How long should we continue the dosage or how many days?
Expert:  PitRottMommy replied 2 months ago.

Most antibiotic treatments last at least 7 days. You need to continue dosing at least 48 hours past symptom resolution.
