Must be the name - I've got a 5 month old called Mollie and she is exactly the same!!!!!!!
Inside she is fine mostly - she doesn't chew furniture etc - it's her recall, lead training etc.
Will be watching replies with interest as nothing is working!
You need to practise, practise and practise but in short sessions, a couple of times a day.
Make it fun, for recall use a long line and practice in the garden, but use your tone of voice to make it sound really exciting to come back to you (your neighbours do get used to this after a while, trust me!
) and praise like mad when she gets it right.
Whenever you're feeling downhearted about it (and having spent the last year working on getting Amber to walk nicely on a lead, I can appreciate how frustrating it can get), just remember that the work you're putting in now will be worth it. No-one gets a well behaved, well trained dog without putting a lot of time and effort in. But the effort you're putting in now will pay you back a thousand times over in the future.
