I can definitely give you recommendations to minimize infection and reduce healing time but if there is discharge or it is not healing then please have your vet evaluate the dewclaw to ensure additional medication is not warranted.
1.) No licking! Please put a sock on or a cone to prevent her from reaching the area. Licking introduces oral bacteria to the area and can increase risk of inflammation and infection which maybe the cause of the swelling or the swelling is causing her to lick...
2.) Trim the hair if needed to minimize trapping in of the moisture with the hair matting. Please use caution with scissors
3.) Use ivory soap and water or dog oatmeal shampoo to the area twice daily with ten minute contact time before rinsing and tap dry
4.) I prefer to not apply salves or ointments because it traps in moisture to the area and reduces healing or delays healing time. If needed you can put a very thin layer of a triple antibiotic on the area after cleaning
5.) Remove any scabbing that occurs with healing. Again it also traps in moisture and then can actually abscess but unlikely with this being a dewclaw
6.) Limit activity. The more activity the more likely this wound will take longer to heal because the skin cannot heal in an active setting, particularly on the dewclaw.
7.) You can do epsom soaks of the foot to reduce swelling as well as rotating warm and cool compresses to help with discomfort and stimulate healing in 10 minute intervals
8.) Since there is licking or rubbing please begin benadryl 1 mg/ pound every 8 hours for reducing the itch but may cause mild sedation.
Please let me know if this information makes sense and any additional questions i can assist with or clarify today.
