Hi, Thanks for writing your query. After reading your post, it seems that you have suffered from soft tissue injury in your breast and needs medication. You should apply locally antibiotic ointment. Anti-inflammatory medicines like Ibuprofen twice a day after meals along with serratiopeptidase and an antacid will help in reducing the pain and swelling. Antibiotic may be needed if it is infected. You can go for a clinical examination by your doctor. I hope your dog must be properly vaccinated and I would suggest you that you should get yourself vaccinated by antirabies vaccine after discussing with your doctor. I hope this is helpful to you. Thanks.
