I can't. Like at all!
She sleeps and naps alone but when she's awake she cries if i leave long enough to visit the loo!
I'm going to seek proper professional help and I've looked at resources online. But how did you get your dog used to being left?
So as not to drip feed she's nearly 18 weeks. A giant breed. We also have cats and kids so I can't let her have completely free roam in the house!
