Fear and Anxiety
Unfortunately, if your rescue pup doesn’t quickly kick their poor sleep schedule, or genuinely seems like he is always sleeping for more than 13 hours per day, fear and anxiety could be the reason. Rescues dogs that were abused or raised in poor environments may have developed fear and anxiety problems that prevent proper sleep.
If your dog is anxious and has trouble sleeping, they may be spending a lot of time lying down, trying to catch up on their missed sleep. Other dogs may have been abused at night or may have other triggers that are preventing their sleep at certain times, so they are trying to catch up at other times. A good dog trainer should be able to help you identify what’s causing fear and anxiety in your dog and teach you how to calm them so they can sleep.
Senior Dog Lifestyle
Is this your first time adopting a senior rescue dog? If so, you may be surprised at how much more an older dog may sleep. Sleeping an hour or so more than a younger dog is common for older dogs, and not necessarily a sign of health problems. As with humans, the older a dog is the lighter their sleep and the more time they need to spend resting to feel rejuvenated.
If your rescue dog is still sleeping too much, even after an adjustment period, it’s a wise idea to get them checked out by a vet. Sleeping too much can be a sign of several dog health issues, but it’s impossible to know if your dog is suffering from one without getting a check-up.
