I can't really come up with anything that's to crazy for a greyhound owner. Maybe for a non grey owner. But here goes:
When we got our first grey, I realized the new floor lamp shined in her eyes when she layed on her bed. So, got another floor lamp.
When 2nd grey came, needed a loveseat so we'd have more room on the couch.
When the 3rd came, we got a new, longer couch for the room. Also bought my former bosses suv to haul them.
When the 4th came, we got a second suv, a little bit bigger for more room.
When the 5th greyhound came, we hadn't had the second suv for a year, but we did trade it in for a mini-van.
We, like all greyhound owners, are always doing something to make their lives easier.
Buying things like collars are another story.
