Hi I am looking for any advice or tips on helping my with my 5 month old puppy. He is crate trained and has no problems sleeping in his crate. The only issue we have experienced is that he is waking up every morning at 4am and howling (we are up just after 5am for work). He is taken out between 11-12.30 for the toilet before bed so don't feel this is the reason he is howling. Can anyone recommend anything that I should be doing to stop this? I know he is still very young and will hopefully grow out of it but just don't want it to become a bad habit. We have been ignoring him and not responding to the howling but the lack of sleep is definitely taking its toll! His crate is in a separate room from us and we have purchased a black out blind as thought the light mornings were the cause, however, this has made no difference. Any advice and tips would be much appreciated.
