I have mailed you lis, been away on my hols! stay away from the spray collar although a muzzle introduced over time in a positive way may make you feel more at ease.
What you have to realise though is that Dora is not just any old dog.
She obviously has issues and it is up to you to manage her life so it is as stress free as possible.
give me a shout I've sent you my number.
