hip dysplacia and dislocating shoulders

as a few of you may know Henna my 10 month old irish setter has hip dysplacia, well we have now discovered her front shoulders dislocate when she lays in a certain way too so its very hard for her to get up. She is very wobbly at the moment and i know she needs more pain killers but i really dont know if i can cope with her being like this for the rest of forever, its not that I cant cope with her but more i cant cope with seeing her like this as i feel its no life for her but dont know what to do, i feel horrible about it all and cant think straight.

Are you sure they dislocate?
I had a Rottie with hip AND elbow displacia. He had to have surgery for his hips. His elbows weren't terrible, after full recovery from surgery and being able to use his back end more his elbow problem was only noticiable if he ran or played to much.

this photo sort of shows it but it comes out alot further usually and also goes up under her chin.

she is being treated by my vet and has been for some time, she is on all sorts of preps and other than operate there is nothing more we can do other than make sure she is comfortable,
I know many are probably thinking she should be put down full stop but i keep thinking maybe she will grow out of it (i know she wont) maybe its not as bad as i think etc, i have talked to my vet several times but im not ready to let her go (yes im selfish) i cant let go of the hope she may be ok and i will have put her to sleep unneccasarily.
