So happy to hear you finally found your dream dog! I'm sorry to hear about her discomfort though. They sell this stuff online called Malacetic ultra! It's very strong and only to be used in a situation like this not for everyday cleaning. I used it on Winston and it did work for a bit but eventually we had to take him to the vet to get meds. Unfortunately when the pocket gets brown and gunky like that it could already be infected or on its way there. Good news is after 2 weeks of meds he is good as new! After you get the infection cleared up you can use witch hazel or raw apple cider vinegar for cleaning. Good luck!! I sure hope she feels better soon!
