When you put her in the tub-is that an actual bathtub? We have had this problem in the past and had to put him in a tote with a lid to keep him in the water. BTW-one of our burms had a burn mark on him when we got him and the vet told us to put a thin layer of Neosporin on the wound to help it heal-and it worked. The cut healed quickly and did not scar near as bad as it could have.
