Unfortunately, the owner of the dog is moving this weekend (absurd to me that they didn't find a home for this good boy yet). After discussing it further, we decided we would take the new dog in and do our best to make our schedules work with his needs. He got along pretty well with our current dog when we introduced them and even when we brought him into our home with our current dog. We are considering doggy day care a few days a week for him so he won't be stuck in the crate for long hours every day.
Our back yard has a short fence, only 4 ft. I would never assume that is safe for either dog. I've always walked my current dog whenever he needed to go outside, always once in the morning, once when I get home, and once before bed (sometimes more). Making more time for walks shouldn't be a problem and its a sacrifice we're willing to make. We have a nice park nearby that I let him off leash sometimes, but from what I've read, you should never let a husky off leash.
The ULTIMATE goal would be to allow the husky to have free roam of the house along with our current dog while we are at work. We are thinking of setting up a camera and leaving him alone for short periods of time and monitoring his actions. Over time we would increase these time periods that we are gone and see how he handles it. If it doesn't work out and he becomes destructive, than we will find another solution.
Thanks for your input! I'm sure we are in for a rude awakening.....
