I could never figure out why people think that you must have a big garden for a big dog or a small garden for a small dog.
When we open the back door the dog rushes out down to the end of the garden, hoping to catch some cats trespassing on his turf. He then does his business, has a sniff round for a few minutes, and then normally comes straight back up to the door whining to be let back in. He won't come in when you open the door, basically he just wants us to leave it open. He comein in eventually.
A few minutes later, he's back standing at the door, looking to be let back out again. He has us well trained.
