  1. What happens to your blood when you become dehydrated? Blood contains: Red blood cells. White blood cells. Platelets. Plasma, which is mostly water. Proteins, electrolytes, nutrients and other substances. When the body loses too much water, plasma volume can decrease. This can cause hemoconcentration, meaning some substances in the blood appear more concentrated. Possible effects include: Increased blood viscosity under some circumstances. Reduced circulating blood volume. Increased strain on the cardiovascular system. Reduced blood flow to organs in severe dehydration.

Why Is My Older Dog Restless at Night?

 

Has your older dog started pacing around the house, wandering from room to room or waking you up during the night? Perhaps your once-peaceful companion now whines, pants or struggles to settle down.



Night-time restlessness can become more noticeable as dogs grow older. However, it should not automatically be dismissed as a normal part of ageing. Pain, changes in the senses, medical conditions and changes in brain function can all affect a dog's sleep.

Understanding the possible reasons is the first step towards helping your dog rest more comfortably.

1. Your Dog May Be Experiencing Pain or Discomfort

Older dogs can develop joint problems, arthritis, dental disease and other conditions that make resting uncomfortable. Your dog might lie down, get up again, change sleeping positions repeatedly or hesitate before climbing onto its bed.

Some dogs also become restless because they need to urinate more frequently or have difficulty finding a comfortable position.

How you can help: Provide a supportive, comfortable bed in a quiet area. Make sure your dog can reach its sleeping area without climbing stairs or walking across slippery floors.

If the restlessness is new, persistent or accompanied by stiffness, panting or difficulty moving, arrange a veterinary examination.

2. Changes in Hearing and Vision May Cause Anxiety

As dogs age, their hearing or eyesight may decline. Familiar surroundings can become harder to navigate, particularly at night when lighting is poor.

Your dog may become startled by unexpected movements, hesitate in dark hallways or feel uneasy when it cannot locate family members.

How you can help: Use a gentle night-light, keep furniture in familiar positions and provide a clear path to the water bowl and toilet area. Approach your dog calmly so that you do not startle it.

Avoid leaving your dog in unfamiliar surroundings if it is already having difficulty seeing or hearing.

3. Your Dog's Sleep-Wake Cycle May Have Changed

Older dogs may sleep more during the day and become more active at night. Changes in daily routines, reduced daytime activity and certain medical conditions can contribute to disrupted sleep.

A dog that naps for long periods throughout the day may have less need for uninterrupted sleep at night.

How you can help: Maintain a consistent daily routine. Offer gentle walks, sniffing activities and quiet interaction during the day, according to your dog's physical ability.

Avoid strenuous exercise, especially if your dog has joint pain or other health problems. The goal is comfortable daytime activity, not exhaustion.

4. Canine Cognitive Dysfunction May Be a Factor

Some senior dogs develop canine cognitive dysfunction, a condition associated with age-related changes in brain function. It can affect memory, awareness, sleep patterns and interactions with family members.

Possible signs include wandering at night, appearing confused in familiar rooms, staring at walls, becoming unusually vocal or forgetting previously learned routines.

These signs can also occur with other illnesses, so they do not automatically mean your dog has cognitive dysfunction.

How you can help: Keep daily routines predictable, provide familiar sleeping arrangements and use gentle reassurance. Record changes in behaviour and discuss them with your veterinarian, who can investigate other possible causes and advise on management.

5. Your Dog May Need to Go Outside More Often

Some older dogs need more frequent toilet breaks because of changes in bladder function or medical conditions that increase urination. Digestive problems can also make it harder for them to remain comfortable throughout the night.

If your dog repeatedly asks to go outside, has accidents indoors or begins drinking noticeably more water, pay attention to the change.

How you can help: Offer a toilet break shortly before bedtime and make the route outside safe and easy to access.

Do not restrict water to prevent night-time urination. Increased thirst and urination can be signs of medical problems that require veterinary assessment.

When Should You Contact a Veterinarian?

Arrange an appointment if your older dog develops persistent night-time restlessness, a noticeable change in sleep patterns or repeated episodes of unusual behaviour.

Seek urgent veterinary care if restlessness occurs with difficulty breathing, collapse, a swollen abdomen with repeated unsuccessful attempts to vomit, severe pain or other serious symptoms.

A veterinarian can assess pain, mobility, urinary problems, sensory changes and other medical causes. Early evaluation may help identify treatable conditions and improve your dog's comfort.

An older dog that wanders or struggles to sleep at night may be communicating a need rather than simply misbehaving. Pain, sensory changes, altered routines and cognitive decline are among the possible explanations.

With a comfortable sleeping area, predictable routines, appropriate daytime activity and timely veterinary care, you can help your senior companion feel safer and more comfortable.

A peaceful night begins with understanding what your older dog needs.
