My dog is in surgery at the moment for this. She got sick and our vet was on vacation. I took her to another vet 4 times over 3 weeks and they never caught it. I was using colloidal silver, coconut oil, and giving her some raw garlic mixed in with her food. We had to hand feed her. The day my vet arrived back he saw her and knew right off what she had. She did need antibotics and this is quite serious. My vet actually yelled at me about being negligent until I pulled out vet receipts for the other vet. The is quite serious and absolutely requires surgery. Antibotics can heal the infection until she is able to have surgery. I had to keep my dog on antibotics for 18 days with the vet seeing her 2 more times during that time until she was able to go in for her surgery.
