Dogs may bark at night for a number of different reasons:
Dogs have extra sensitive hearing:
This is because dogs have such acute hearing. "Although your home or apartment might be very quiet to you, a dog can be extremely sensitive to outside noises and bark in response. Putting on a TV, radio or white noise machine might help block out some of that external noise and hopefully
eliminate this cause of bedtime barking.
Dogs often bark loneliness.They suffer when they are left, especially extending period of time.leaving
the dog with neighbour or bording him in a no-cage cannel overnight, mayhelp roverfearless lonely at
night. loneliness remains one of the top triggers she sees in dogs that can't seem to settle down.
Alarm / perceived intruders/fear:As humans, we fear the unknown, and dogs also feel the same
nighttime anxiety. "If a dog is fearful, they may bark at any noise they hear that is scary to them or startles them.
Allowing your dog to sleep in your room should help to eliminate barking due
to separation anxiety. If sleeping in your bedroom isn't an option, maybe you need another dog for a source of companionship.
Old age / dementia:
This condition associated with old age is known for causing house soiling, changes in the interaction
with people and other pets,activity changes and altered sleep.
If a dog is bored, they are likely to vocalize more often. If dogs are left alone for long periods of time,
they can become very bored, especially if there is nothing for them to do.when they needs are not met , dogs are more likely to engage in problem behaviors such as digging, chewing and barking.
Not enough exercise:
Exercise is the best solution for this cause of barking. One option is sending your dog to doggie day care where they can have a tiring day, running around and playing all day with other dogs. Alternatively, you and your dog can exercise together. A long walk or run will help tire both of you out before bedtime.
