If there is green pus coming from the paw this is an indication of infection that requires antibiotic therapy. I would stop using hydrogen peroxide as it isn't recommended for regular wound cleaning (can actually delay healing if used repeatedly). Clean the area with mild soap and dry well to avoid moisture, apply a topical antibiotic ointment, place an e-collar on your dog to prevent him licking the foot and make an appointment for your dog to see the vet. He likely will need oral antibiotic treatment and the vet will want to check his paw to be sure there isn't a foreign body like a splinter stuck there.

    These signs are compatible with an infection. Drainage of abscess, disinfection and antibiotic treatment are indeed necessary and a check up is what I recommend as soon as possible. Swelling could be due to a lack of venous drainage of the leg (due to the inflammation, so it will resolve when abscess will be cured) or to the spreading of infection. Buster collar may be useful to avoid licking.Disinfection can eventually be started at home with very diluted hibiscrub or betadine or salted water baths. Please do not hesitate to contact us again on the forum or by requesting a consultation if you have any more questions or to discuss it any further.
