Hi, our lovely 11 week old Cockerpoo puppy took to crate training immediately and goes in their happily during the day and at bedtime. He is also excellent at toilet training and wakes us between 2 and 4 am to go for a wee which he does immediately. This last week he will not go back in his crate, he will sleep on our lap but as soon as we try to move him back to the crate he wakes and cries/barks. We have tried encouraging him with a Kong filled with his favourite food but he will leave that as soon as we leave and cry. We have tried leaving him to cry for a bit - he is relentless and it wakes the whole house. Any suggestions, we are getting desperate as we are up all night with him !
