My Mini Moo, had constant trouble for 2 1/2 years she had them emptied , flushed and had a ongoing infection in them, I was advised to think long & hard before we decided to have them removed. It was an horrendous operation and really painful for her, but i dont regret it she still holds her tail quite high but its just a habit she had fallen into because obviously she was uncomfortable before, her movement at the backend improved considerably so she must have been in constant pain.If i had known how much pain she had been in i would have had it done much earlier but i was warned she may not be able to control her bowel, she has had no bad effects at all and she is a much happier little girl no problems with controlling her bowels, hope this helps !!!
