Penicillin is an antibiotic that must be used (legally) under the direction of a licensed veterinarian who has prescribed it for your dog. If a veterinarian were to prescribe injectable penicillin for your dog (which itself would be rare - dogs are more likely to be prescribed oral penicillin since it's easier to administer for most owners), he/she would provide the dosing frequency for you.
There are 3 main types of domestic rat. ~ Brown rat/Lab rat: Rattus Norvegicus ~ Black Rat: Rattus Rattus ~ Gambian Pouched Rat: Cricetomys gambianus Depends if you want a big rat, medium rat, or small rat.
