Poor baby
I wonder if they could use some techniques that they use for humans with hernia/bladder issues. My hubby had a hernia operation 20 years ago where they used a mesh to reinforce the area. He's never had a problem with it again, and he lifts heavy things all day long!
With humans, they use a "bladder sling". Don't know much about this, as they didn't do this for me when I had my full hysterectomy. They usually do this because the organs they remove leave a gap that the bladder slips down into and that causes urinary incontinence (yay me, pee if I sneeze, laugh, cough, or run

!) I wonder if the technology exists to perform a bladder sling on a doggy?
