It appears your walks may be aggravating your hip. Maybe it would help if you shortened your daily walks until after your surgery. Since you have the dogs, you may have to walk but they will be just fine with shorter walks for a time. If you keep aggravating your hip, you may reach a point where you can’t walk at all and that would not be good for you or for the dogs. They will quickly learn that walks now will be shorter. Actually it would be better if you didn’t walk at all except for around the house but maybe that is not possible. Anyhow, you need to baby that hip as much as possible as the more you do, the more the hip deteriorates and there is nothing we can do to stop it. I wish you well.
