Its really not advisable to treat without a vet's supervision Misba. I still recommend you to visit a government veterinary hospital which is nearby. Anyhow the whole pus has to be removed by wearing gloves and wound should be cleaned with Betadine solution. Suturing of the wound may be required and has to be decided by a vet only. Apply povidone iodine ointment with D'Mag spray. Give Syrup Haempyrin (0.5ml, twice a day for 5 days) and syrup Cephavet 1ml, twice a day for 5 days.
