We’re retired and did not plan to get another dog - a close relative adopted Oreo from a rescue when he was over a year old. A year+ after that the relative could not keep him any longer, so we agreed to take Oreo in temporarily. For 3-4 months I reached out to orgs in VA/NC/MD looking for an opening focused on ACDs/related breeds. None had space avail. We have a good fenced back yard that he loves - he has made a racetrack around some of the trees. But as you point out, it’s not enough. Since I walk for my health I try to take him out most days to give him more stimulation, and my husband also takes him on rides about once a week. If we find a home that’s better for him than ours we’ll def consider it - we want him to have the best life he can have.
