Well they shouldn't smell bad that much. We don't bath our bully very much, maybe once a year if that much. Does she shell like fritos? if so she may have a yeast infection. Plus her anal glands may also need to be expressed. Does she scoot her bottom on the ground trying to itch it? That is usually a sign her anal glands needs expressed. You may want to take her to the vet or a groomer to do this for you. You can try some powder on her underside to see if that helps, or some Desitin. Mal-A-Ket wipes also are good to have around and can help with bacteria and yeast. Others will be along to help with the yeast. Rinsing we with a solution of vinegar and water after a bath will help also. I think the mixture is 50/50, but not sure. Someone will be here to give the correct ratio.
