Why Is My Dog Sleeping More Than Usual? Causes & When to Worry

Dogs love to sleep, but what if your dog suddenly starts sleeping much more than usual? In many cases, extra sleep is completely normal. However, sometimes increased sleeping can signal an underlying health problem.

If your dog seems unusually tired, it's important to look for other symptoms and understand what might be causing the change.
