Sometimes having a puppy is just like bringing home a human baby--a lot of sleepless nights while everyone adjusts to the new environment. Because dogs are pack animals, their natural inclination is to sleep with others, in close contact, for safety and comfort. A young dog or puppy is especially geared to sleep closely in a group for safety, and a rescue dog or an anxious or insecure dog that has come from an abusive situation or a situation where they were deprived, may be nervous and anxious and more apt to cry when separated from their caregivers, such as at night when everyone is sleeping.
Having a dog cry at night and keep you awake is not going to work in the long term, so owners need to find ways to train their dogs to sleep quietly at night in their own space, and for the dog to be comfortable with the arrangement, allowing dog owners to get a good night sleep.
There are several methods you can use to help your dog learn not to cry at night and to be comfortable sleeping by himself, quietly. However, before working on stopping your dog from crying at night you will need to take some basic steps to ensure his needs are met and he is not crying for a genuine reason.
Make sure your dog is well fed, has water, is well exercised, and has had lots of attention throughout the day, including affection and play. A dog that has had lots of activity and had his needs met is more likely to have a restful night than one that is full of energy or bored. Ensure your dog has had a chance to go outside to do his business before bed. And remember, a puppy may cry in the middle of the night when they wake because they legitimately have to go to the bathroom. Puppies do not have large bladders, and it is not uncommon to have to let a young dog out in the middle of the night for a pee break. You should work this into your plans if necessary.
Most owners that want their dogs to sleep separately from them provide their dogs with a bed or crate to sleep in. The crate should be comfortable, with good, clean bedding, and a favorite blanket or toy for comfort. Your dog's bed/crate should be in a warm location so your dog does not wake up from cold. Crates or beds should be the appropriate size for the dog, too big and the dog will not feel secure, too small and they will not be comfortable. You may need to be prepared for a few sleepless nights at first, as you will need to ignore and not respond to your dog's crying. If you do, you will only reinforce the behavior. This might call for a set of ear plugs!
There are several methods you can use to help your dog become comfortable and learn to sleep by himself without crying for attention at night. These methods may be used in combination to help your dog assimilate to their nighttime routine quicker.
