The shelters I contacted require us to have a fenced in yard as a condition of adopting, so I've spent the last couple of months reading up on the topic and getting quotes.
Invisible Fence would run about $2,000 and works for most but not all dogs.
Extending our current scrap of fence all the way around the yard, with something that looks really good is almost $8,000.
My question to LJ: how necessary is a fence really (aside from the fact that the shelters require it)?
If I go minimal, what's a reasonable size for a fenced area for a mid-size dog?
