Our 5 month old miniature poodle has started barking at night once he has been put to bed in his crate. This is new as up until now he has been reliably sleeping from 10 to 7 once he is in his crate. My DH doesn’t tend to have the same problem when he puts him down for the night, just me. He has recently been to the vet and his health is good. He is teething a lot though. We check him once in case he needs the toilet. We are then ignoring the barking but it can last a long time (over an hour) before he quietens. Any suggestions would be welcome as it is stressful and noisy for us and neighbours.
