My friends Mom was acting as a 'foster home' for some greyhounds. Figured taking them to the high school and the fenced in football field would be a good place to take them for a run.
Well, all went find until a few deer ran by and the dogs found their way out. This was around dusk.
We spent the next 1-2 hours trying to find and 'run down' two greyhounds.
Luckily the male, like most men, was interested in tv so he started peaking in a sliding glass door. The lady of the house was able to get him, read his tags and make some calls.
Now the female, who was very averse to human males (trainer beat her?) was still on the loose, was a dark gray and impossible to see in the dark. My buddy and I actually walked right by here in the street. Oddly she passed up, then 20 feet beyond us she yelped and then ran to us. Totally out of character but it happened. We just were wondering how lucky we had gotten. It is not like you can 'run down' a greyhound.
Even after this event they did allow his Mom to adopt one. I am not sure if all are this way but he seemed a bit aloof, not social like most dogs but I believe he did come around after some time. I think he had to be broken of being a track dog and the routine he was used to and how to become a house dog.
As far as leaving a dog for 8 hours - invisible fence & a dog door. The invisible fence took what had been an escape genius and the neighborhood dog to one that knew exactly where here lines where and how far should could venture around the property.
Just moved to a new house, laid out the wire around the property, put up the little white flags and did not even have to train her - she remembered that getting close to those little white flags meant shock therapy. I have an appreciation for the shock - I do not know what possessed me but I took a #2 (of 5) shock.
Well that was a diatribe about a whole lot of nothing..........
