We are still having a problem with barking at night (after bedtime) every night he starts barking about 15 mins after lights out. then he wakes up and starts barking about 3 am and then about 5 am.

We have tried not going to see him, leaving the radio on (classic fm, xfm, radio 4 - so a bit of range)

Tried giving a kong toy with puppy paste and kibble in to keep him busy.

It all started when he bad a bad tummy and before that he settled very well at night. I think hes just developed this as habbit now, and I really want to break the cycle before we all get sleep deprived!
