This will depend on the penicillin product you are using and the type of condition you are treating. Different products contain different concentrations of the drug and even different forumlations which require different dosages. There is often a dosing range and the veterinarian makes a recommendation on the dose to use in a given situation based upon the type of condition/infectious organism being treated. Consult your veterinarian to determine an appropriate dosage in a given situation or if penicillin is even the appropriate drug for use in that situation.
This will vary widely depending upon the formulation of penicillin (K-Pen vs Pen G, for example), the route of administration, the bacteria being treated, the location of the infection and the overall medical status of the horse. Also, in the vast majority of countries, penicillin is only to be used under the instruction of a veterinarian who has seen the horse and prescribed penicillin for it. Therefore, your best source of information for this will be your prescribing veterinarian.
As with all drugs the amount you should give will vary according to brand and the type of bacterial infection. You should consult with a equine veterinarian for exact instructions.

i don't recommend it.
You can give any size dog penicillin. It would need 3 mL or 3 cc's.
Penicillin is not always the best drug to give to a horse, you should consult with your equine veterinarian to get an exact idea of what medicine should be used for the ear infection.
Check the label...it depends on the concentration of the solution you are using...
Subcutaneously means uinder the skin.
You should not give a horse oral Penicillin. Oral Penicillin can seriously disrupt normal microorganisms in the digestive tract which can cause diarrhea and abdominal pain (colic). For an abscessed tooth you may need to give Injectable Penicillin, but never oral. It would be best to contact a equine veterinarian and possibly an equine dentist, as the tooth may need to be removed.
Penicillin needs to be injected intramuscular so the breast works really good or divide the dose into two and do one shot in each leg up in the muscle

You should not give horses Penicillin for a cold, as a cold is caused by a virus and Penicillin is an Antibiotic and is not designed to treat a cold. You must let the cold run it's course, just like in a human.
The amount of penicillin and the length of time to give it will vary somewhat with the brand used. It would be best to consult with a equine veterinarian regarding dosage and length of use.
First you should have a farrier and veterinarian come out and inspect the hoof for deeper infection. Once this has been done the equine vet will be able to give you exact dosage and time limits on the penicillin.
