My cockapoo puppy is nearly 7 months now and is barking to get us up earlier and earlier. For a couple of months it's been about 630 which is fine as were up at 7 anyway, so we've been setting an alarm and getting up then which was often before he stirred (so trying not to reinforce the barking). But it's getting earlier and earlier now it's getting lighter and is currently at 6ish. She makes a massive noise barking and howling so we can really leave her as we have attached neighbours. She does need the toilet (both poo and wee) but the fact that it's getting earlier must mean something is waking her. She's not hungry and doesn't get fed till about 7. She has a blackout cover on her crate so it's not the light. So it's possibly the birds waking her or needing the toilet (but would that actually get earlier all the time rather than improving?). Help!
