True or False?

All modern dog breeds descend from a single wolf population.

(scroll to the bottom to find the answer!)

The next time your dog does something that makes you feel like you have truly known each other forever, you might be onto something. The largest-ever study of ancient dog DNA found that at least five distinct dog populations existed at the end of the Ice Age, around 11,000 years ago. Each had its own lineage, descended from a now-extinct wolf, and all were already widespread across the northern hemisphere.

The research, led by scientists from institutions including the University of Oxford and the Francis Crick Institute, analyzed 27 genomes of ancient dogs from Europe, Siberia, and the Near East. What they found was fascinating: the diversity you see in dogs walking down the street today has roots that stretch back to the Ice Age itself.

Those ancient lineages did not disappear. They mixed, traveled, and evolved alongside us. The Chihuahua, for example, traces most of its ancestry to Europe but carries traces of pre-Columbian DNA. The Rhodesian Ridgeback is mostly European in lineage but carries ancient Middle Eastern or African ancestry too. As one researcher put it, dogs are our oldest animal partner, and every pup walking beside you today carries that shared history.

As our dogs get older, they start to change in small ways. Maybe they take a little longer to get up in the morning, prefer shorter walks, or sleep more than they used to. These shifts are a natural part of life, and noticing them early is one of the kindest things you can do for your pup.

Some common signs that your dog may be entering their senior years include moving more slowly, having cloudier eyes, sleeping more, or being a little less interested in food. None of these mean anything is wrong. They are just gentle cues to pay a bit more attention and talk to your vet about what support might help. A few things that can make a real difference:

• Adjust exercise gently. Shorter, slower walks are still walks. Swimming is another wonderful low-impact option many older dogs love.

• Consider supplements. Joint supplements are commonly recommended for older dogs and can help with mobility and comfort. Ask your vet what makes sense for your dog's needs.

• Make home more comfortable. An orthopedic bed, a ramp instead of stairs, and keeping food and water in easy-to-reach spots can go a long way.

• Keep up with vet visits. Senior dogs benefit from more frequent checkups, which can catch changes early and keep them feeling their best.

The golden years with a dog are something truly special. A little extra care goes a long way toward making sure your pup enjoys every single one of them.

As pet parents, it's easy to assume our dogs slowing down is just part of getting older, but the changes often start earlier than people think. Dogs can begin showing signs of aging around age 7, and by 8-10 years old, many start experiencing cognitive decline similar to dementia in humans. This can show up as confusion, disorientation, or restless sleep. Because these changes happen gradually, it's easy to miss them until they're harder to ignore.

That's why PawPrint Lab created Pawprint Protocol, a daily liquid supplement that supports your dog's healthy aging from the inside out.

Meet Bear, an almost 8-month-old Havanese who arrived in Daily Dig reader Marisa's life at exactly the right time. After losing her previous dog two years ago, Marisa says Bear has brought a whole lot of joy back into her home, and honestly, one look at this little guy and you completely understand why.

Bear is a social butterfly who wants everyone to say hi to him or play with him. Marisa especially loves his little white eyebrows and the whitish-grey socks on his paws. He is the kind of puppy who makes you feel like the world is a pretty good place just by being in it.

🤔 True or False: False! While all domestic dogs descend from a now-extinct wolf ancestor, the largest-ever ancient dog DNA study found that at least five distinct dog populations already existed 11,000 years ago, each with their own separate lineage. The story of dogs is a lot more complex and fascinating than we ever imagined.
