Puppy has oozing skin sores and fleas. How to treat at home?
Oh dear, poor Peanut! Some dogs are allergic to fleas and can actually develop bacterial skin infections as a result of ongoing scratching and licking. The first two photos look most suspicious for signs of a skin infection, but the third photo looks more suspicious for a raised benign or malignant mass. I'm glad that you're planning on taking Peanut to his vet when it is financially feasible for you. In the meantime, make sure that all pets in your house have been treated with a high quality flea preventative, such as Nexgard, Bravecto, or K9 Advantix II (or Advantage, Revolution, or Bravecto for cats if you also have cats in the house). You can also give your dogs a dose of oral Capstar ( http://www.drsfostersmith.com/product/prod_display.cfm?pcatid=10902 ) to rapidly kill adult fleas in addition to the flea preventatives mentioned previously. Be sure to use these flea preventatives regularly without missing doses to break the flea life cycle! For Peanut's irritated skin, you can try bathing him in a medicated antimicrobial/anti-itch shampoo ( http://www.drsfostersmith.com/product/prod_display.cfm?pcatid=27981 ). Hydrogen peroxide can actually delay skin healing, so I would avoid further use since it is likely to cause more irritation. I hope this helps and that all goes well!
