Julie...First welcome to EBN Jewel and Bentley say hello to you and Harley.
I very much sympathize with you and Harley's quality of life. Our Jewel (3years old now) has had the surgery. Most recently, our boy Bentley (2.5 years old) is now having an issue and will be evaluated in one week by an Ortho. In addition, there are many EBNers whose fur babies have gone through the surgery as well as yourself and are fully aware of the rehabilitation process.
It is a big dilemma that you are faced with. If Harley is the running type of bulldog that my Bentley is (aka Ball Junkie), I would most likely talk to your vet and get his/her opinion on surgery. If Harley is more like a couch potato like me, then I would think some pain pills and rest is in order (in both cases). You can try the brace and see if Harley can do the things he like to do. Essentially, what will be Harley's quality of life with or without the surgery. You and your husband should weigh the options see what Harley thinks. Most definitely talk with your vet.
I hope this helps. --rj
