Jessie's mum and dad are in a yard that is only 3 feet high believe it or not. And they don't get out. They do live at the end of a road, though there is a walking track that starts at the end of their road so they get walking traffic going past. And a school at the rear.
I had a three foot high mesh fence before we got the six foot fence put in. It wasn't only for Jessie that I had it put in, but I just didn't feel comfortable leaving her in a yard with a mesh 3 foot high fence. So far she is only 7 and a half months. If she starts to jump the fence I'll have to contain her in a smaller area, but my main job is a mum, so I'm home most of the time, and tend to only go out for 2-3 hours at the most, and not every day. There's no one at home to keep her in the house while I go, except on weekends when my husband is home, and we do keep her in the house while the other one goes.
This whole training business is so dispiriting. Although we have been haivng fun with roll over and shake hands. She picked that up very fast, unlike walking on a loose leash and come!
