Friend, what you are describing in Dozer is consistent with pododermatitis which basically means inflammation of the paws. The skin in his body being affected suggest that this could be related to an infection, underlying allergies, etc.
Dozer will benefit from oral prescription medication (antibiotics, anti inflammatory, etc.) from family veterinarian. In the meantime this is what you can do:
1- Change his diet to a prescription food called Hill's z/d or a grain free diet with a different source of protein then what he normally has had in the past. For example: If he seldom ate fish then put him on a food that has fish. When on this diet he should not eat anything else or he will not improve. No people food. Needs to be on this diet for 6-8 weeks before you see significant improvement. For treats you can give veggies like: Baby carrots, broccoli, cauliflower, etc.
2- Start him on Benadryl (diphenhydramine) 25mg 5 tablets every 12 hours. You can buy benadryl over the counter in any pharmacy.
3- Supplement with Eicosaderm (omega 3 fatty acids); you can buy this over the counter in any pet store or online. Give at label dose.
For his paws this is what you can do:
1- Need to stop him from licking or he is going to delay healing. Pick up an ecollar (cone) in your local pet store to stop him from licking/gnawing at affected area.
2- Pick up in your local pharmacy "Hibiclens" antimicrobial soap or chlorhexiderm scrub. Dilute 1-2 tablespoon for every cup of water. Use this mixture to soak his paws for 5 minutes 2-3 times a day.
3- After soaking paws apply a topical antibiotic like neosporin or bacitracin. Do this 2-3 times a day for the next 7-10 days.
4- Follow up with your family veterinarian.
