Hi Meriam, Your dog and its care is totally up to you. The decision for THR is one that must not be made lightly. THR will not restore full function to your dog and though the technology is getting much better I am not a proponent of these types of invasive procedures. Though I love my dogs dearly I would not put them through that trauma - I would put them down if any injury or condition dictates that they cannot function reasonably anymore. Many will disagree but like I said earlier it is totally a personal choice. As you assess your dogs and your situation it is best to think longterm and see if the pain and expen$e is really worth it. Sorry If I am not much help. You have a very difficult decision ahead of you - personally I would not do it. Good luck.
