I unpicked the tail. I took the stuffing out of it. I cut some coathanger wire and put it in the tail. I re-stuffed the tail (less stuffing this time). I re-attached the tail and put some bends in it. I am now happy with the tail :-D
Here she is, my little dalmatian.
I also ended up making a quicky skirt for her to wear when she took the suit off so she could still be dressed up for the day but the suit was on almost all day anyway.
