So you've decided to bring a dog into your life. Brilliant news. While puppies tend to get all the attention, shelters across Australia are full of wonderful adult and senior dogs who'd make incredible companions, and they're often the most overlooked. If you're weighing up your options, here's why adopting an older dog might be the best decision you ever make.
What counts as an adult or senior dog?
Most dogs are considered adult from around 1 to 7 years, and senior from roughly 7+ (smaller breeds age more slowly, large and giant breeds tip into senior territory a bit earlier). Either way, they've moved past the puppy stage and into the calmer, easier years.
1. You'll know exactly what you're getting
One of the biggest perks of adopting an older dog is that their personality is already there for you to meet. Whether you're after a couch companion, a beach buddy, or a quiet little shadow who follows you from room to room, you can pick a dog whose vibe genuinely matches yours.
There's no guessing how big they'll grow, how much energy they'll have at two years old, or whether they'll be a cuddler or a zoomer. With an adult dog, the personality test is already done.
2. Toilet training sorted
Most adult dogs up for adoption have already cracked toilet training. That means fewer accidents on the rug, fewer 6am dashes to the back door, and a lot more time for fun stuff like walks, pats and snack negotiations.
If your new mate needs a little refresher in their new home, that's normal and usually pretty quick to sort out by revisiting toilet training guidelines.
3. Less chewing, less chaos
New puppies are adorable but they're also tiny chaos agents. Adult dogs are far less likely to chew on your favourite shoes, eat the corner of the couch, or redesign the garden one hole at a time.
If you work out of the house, have a busy week, or just like your skirting boards in one piece, an older dog is a brilliant fit. They're generally happy to nap while you're out and greet you at the door like you've been gone a week. (If your adult dog still likes a chomp now and then, our guide on how to stop inappropriate chewing has you covered.)
4. You'll actually sleep at night
New puppies can take weeks to settle, and they often need a toilet break or two in the wee hours (no pun intended). Adult dogs, on the other hand, are very on board with the concept of a full night's sleep. Most are perfectly content to tuck themselves into a cosy bed and snooze through until morning.
If your sleep is precious, this one's a game changer.
5. They've got so much love left to give
There's a real myth that older dogs are somehow "broken" or "set in their ways". The truth is, most adult and senior dogs are loving, social and absolutely ready to bond with a new family. Many of them seem to know they've been given a second chance, and the gratitude shows up in every tail wag and lean-in cuddle. Senior dogs in particular are some of the most affectionate, easygoing companions you'll ever meet.
6. You're literally saving a life
Adult dogs have a much lower adoption rate than puppies, and seniors lower still. They end up in shelters for all sorts of reasons: a previous owner moved overseas, a relationship broke down, or sadly, their elderly person passed away. None of it is their fault.
When you adopt an older dog, you're not just giving one pup a home. You're also freeing up a spot at the shelter for another dog who needs it. It's a two-for-one act of kindness.
A few things to think about
Older dogs sometimes come with a bit of medical history, or a few quirks from their previous life. It's worth booking a vet check shortly after they come home, or better yet, adopting from a shelter who has vet-checked them already. That way, you've got a clear baseline of their health. Give them time to settle in too. Some dogs blossom in a few days, others need a few weeks. Patience pays off every single time. Our article on common shelter dog behaviour problems and how to address them is a great primer.
