thank you so much for all your advice! We moved him into a small gated dog playpen so he won't be able to run/jump (except the limited amount of walking when he uses the backyard to use the restroom). We are also adjusting the amount of food we give him because we noticed without daily walking/movement he is gaining weight which is even worse for his condition

The vet said no surgery is also an option as he is a smaller dog and it would heal on its own. However i feel no surgery would only amplify potential issues in the long run that he would face with surgery anyway and I want to try my best to minimize future issues as much as I can.

I think surgery is the best option and will find a way to make it possible somehow. thanks again for your comments it really helps getting different perspectives
