It's good that you have access to vet care, hopefully you can get some medication and begin treatment.we do have access to pretty much medicines here.But what we use best as an antibiotic is augmentin. So i'll try to give her this or any other antibiotic as prescribed by the vet. Another point is the vet here are much cheap so we have access to them all the time not worrying for the expense.
Please keep us posted.
