Dogs thrive on consistency, and even a one-hour time change can throw them off balance. Dogs are creatures of habit, especially when it comes to mealtimes. Their metabolism and hunger cues align with their internal body clock, so when the schedule shifts, they may either beg for food earlier than usual or show less interest in their meals. If your dog is used to eating at a specific time, the clocks changing can make them feel like their meal is late (or early), causing restlessness, whining, or even digestive discomfort. Dogs rely on routine to feel secure. When their daily schedule shifts without explanation, even by an hour, some dogs may become anxious or confused, leading to pacing, whining, or attention-seeking behavior. Lack of sleep or inconsistent rest can lead to increased stress, irritability, and even behavioural issues in dogs. This disruption can lead to pent-up energy, frustration, or even behavioural issues like excessive barking or chewing. While the clocks changing may seem like a small shift to us, it can feel like a big deal for our dogs.
