Honestly it depends on how dedicated you are to wanting to keep the dog. Dogs are a lot more work than people think and the work never ends. Even the best trained dog needs constant refresher training and working breeds like you have don’t slow down with old age.
It can however be done.
I work full time and my dog is never destructive to the house, however I work very hard to full fill her needs.
To offer a different and potentially controversial view to most people, you can leave your dog for a few hours either side of a dog walk. I leave at 8am, dog walker comes and takes the dog midday for an hours walk, and I get home at 5pm. But this took time to build up to and is the tip of the iceberg in what she does in a day.
I crate trained my dog to begin with. It gives them somewhere safe to go and sleep but also stops them from destroying the house when you aren’t there. But you can’t leave them in the crate for too long, especially when young. You will need to pay someone to walk them twice a day or one walk and one check in visit at the very least. It all depends on how long you are gone for. You can build up how long you can leave them but it takes time and not every dog copes with being left alone. You need to be prepared to potentially pay for two walks a day or a good day care for the rest of the dogs life.
But it also doesn’t stop there. That isn’t enough and you will still need to do more when you get home. Ask yourself if you can do similar to the below for the next 10+ years.
On top of the hour off lead walk she gets with the dog walker, every day after work I walk my dog, practicing lead walking around the block for half an hour. When we get home, I use my dogs dinner portion to do 10-15 mins of training. Once a week I also attend agility training and a scent work class. At weekends we go on hikes, we go to the beach, and we do training as well (attend a group obedience class).
Basically my whole life outside of my job is full filling my dogs needs. She is happy, never destructive and calm inside the house because she has enough to do both physically and mentally.
It costs a lot in both time and money but it is so worth it. She is a fantastic dog who lives the happiest life.
It all boils down to, are you prepared to give that amount of time and effort to your dog for the rest of its life?
If no, then there is no shame in rehoming to someone that can/will. Do it now while they are still young and desirable to adopt. The longer you leave it the worse their behaviour will get and the less chance of them being rehomed successfully.
