We just got a rescue dog. She came from abroad, was a stray and is ~6 years old.
We created a safe space for her under the stairs, closed with a canvas type of gate, and she stayed there for the first 24h, just out to the garden for wees. 24h in, which was yesterday at 4am, she got really unsettled, managed to get out through under the gate and rushed downstairs, thrashing against the garden door to get out. We thought she was desperate for a wee and took her out, but she really just needed to get out. Probably not used to being indoors.
Last night we decided to put her bed downstairs, to avoid the mad running down the stairs in the middle of the night, but again she did the same thing, completely desperate to get out, pushing against the blinds :-(
Now in hindsight I really wish we had got a crate, we just thought the safe space under the stairs would work better, but is it too late now? We really want to get one but don't want to cause any additional stress...
Any other suggestions or ideas? I have experience of dogs but maybe underestimated what it would be like bringing a 6 year old stray into a small house :-)
