When we first brought Mandy home as a small puppy, we agreed she was not to be a house dog; my husband has a real problem with animals in the house. However, living as we do in the country where everyone lets their dogs and cats roam free, it presents a problem, because puppies have no idea of boundaries. So if they see something tempting on the other side of the road, or another puppy next door, they'll go check it out. I've suffered so much aggravation from other people's dogs killing chickens, pooping in my yard, and chasing my cattle that I did not want my dog causing this kind of grief for others. So Cliff built Mandy a nice pen in the barn where we can put her when we leave. Later we found out that even when we're outside with her, Mandy will invariably run next door, where a neighbor puts table scraps out for her own pets... and while she's there, she usually runs into their puppy and forgets to come home. So, we bought a lead and stake to tie her outside sometimes. However, it's no fun to have a dog if you can't enjoy them, so early on, I started letting her in the house. Cliff's gone when I get home from work, and it's nice to have some company. At Cliff's request, I kept her off the carpet, which means she can't go into the bedroom or living room. At first she found a throw rug in the kitchen that she liked to lie on. By her second day here, she understood she wasn't allowed in the carpeted rooms, and never entered them at all; she's a very bright dog and learns fast.
Soon, though, we noticed she'd lie down on her rug in the kitchen with only her head on the living room carpet. Cliff said, "Oh well, that doesn't hurt anything." (In all honesty, he'd rather she wasn't in the house at all, but he likes to see me happy.)
We'd never see her actually moving on into the living room or, later, the bedroom... but we'd notice that somehow she would creep in farther when we weren't looking, inch by inch, till not even the tip of her tail was left in the kitchen. We'd holler "get back" and she would. But within twenty minutes, you'd glance her way and she'd be at least halfway back into the living room!
I took this picture a few minutes ago; she's sound asleep in the bedroom, just across the threshold from the kitchen. You'll notice that she is 100% in the bedroom! She is certainly persistant, isn't she? And the thing is, it works. We look at her and say, "Well, as long as she doesn't go any further...".
One of these days I fully expect to see her on the bed or couch, and we'll just sit and wonder how she got there.
