The top 10 big dogs that need adopting

Big dogs, you are beautiful. From lengthy limbs to those panther-like paws, big dogs have a whole lot of lofty love to give.

We’re bringing you the top 10 big dog breeds in our care that still need their rehoming heroes. This, and all the info you need if you’re thinking about becoming one.

What are the biggest dogs in the world?

As the answer is widely disputed, we can’t know for sure which large dog breeds are the biggest in the world. What we do know is which large dog breeds in our care need their human heroes the most.  

So, we’ve put together a list of the 10 big dog breeds we care for the most in our rehoming centres. Could you give a humungous hound a home? 

Is a big dog right for me?

All dogs have their own wonderful and unique personalities. But there are still some practical things to think about if you’re considering one on the larger side.

Food and vet costs, for example, are likely to be greater for large dogs. But caring for them is often no more work than caring for a small dog. Some large dogs can be laze-machines, so they don’t necessarily need more exercise either.

Big dog breeds in our care: the top 10

Our rehoming centres care for more large dogs than any other size of pooch. And they make up the largest proportion of our Underdogs – dogs who’ve been looking for love for over six months.  

Here are the 10 big or giant dog breeds (and crossbreeds) that usually make up the largest chunk of dogs in our care. 

Greyhound

Despite their athletic build, Greyhounds don’t necessarily require endless exercise. Some enjoy a good run, but many will be happy with a leisurely stroll. After their exercise needs have been met, they’ll probably show you their snoozing skills.

Lurcher

Yes, some Lurchers are on the taller side, but they don’t need a mansion. Like all dogs, they just need enough space to comfortably sleep, eat, play and relax. You may need to keep an eye on curious noses at the table. But there are benefits too, like not having to bend over so much to clip their lead on.

Lurchers don’t shed as much as many other dogs. So, you won’t need the hoover out every day with one in the house. 

German Shepherd

Sometimes called Alsatians, German Shepherds make up roughly 5% of all dogs in our care (as of January 2025).  

These dogs often have bundles of energy and love to get stuck in. They’re sometimes seen accompanying emergency services on rescue missions. But many of them need their own hero. Could you welcome a shepherd into your flock? 

Labrador Retriever

What’s not to adore about a Lab? As one of the UK’s most popular breeds, Labradors have a reputation of making faithful family companions.  

Labradors aren’t usually tall. It’s their overall size and weight that lands them in our big-list. But they can still put you through your paces in the great outdoors.

Are you ready to retrieve your next pal? 

Siberian Husky

Huskies have a thick double coat to keep them warm in cold weather and cool in the heat. So, they’re officially the world’s cosiest dogs (okay, it’s not official).  

But if you’re searching for your next adventure buddy, then look no further. Huskies typically have can have high energy levels and love long walkies, making the ideal exploration partners. Be a Husky’s hero today. 

Crossbreed

With a large crossbreed, you get the mystery of several pups in one. Are they a Collie? A Doberman? Who knows! That’s the beauty.  

Each one as unique as the next, crossbreeds are the dogs we see the most of in our care. Could one of these loveable rogues suit your lifestyle?

Belgian Shepherd (Malinois)

Looking for a furry friend to match your energetic lifestyle? Malinois dogs make loyal companions and are some of the most highly driven pups around.  

You may have seen them lending a helping paw on police missions. But they make the best partners in crime in a loving, active home.

Rottweiler

Rottweilers can be the ultimate snuggle buddies. But whether it’s a sofa snooze or a long walk in the country, you can count on them to get involved.

They may not be as leggy as some of these other breeds. But Rottweilers are by no means small. Could you welcome a larger-than-life pal into your home?

Mastiff

Remove the ‘t’ from Mastiff and you get an idea of just how big these charming giants can be. But despite their striking stature, these pooches are often snooze specialists once their bodies and brains have had enough engagement.  

Some doggies just love to laze. Could a mastiff be your new sofa sidekick?

Italian Corso Dog

Like the Roman empire two thousand years ago, Italian Corso dogs are large and ready to march.  

More widely known as Cane Corsos, these magnificent mutts need plenty of physical and mental stimulation. So, they’ll be sure to keep you on your toes. Could a colossal Corso fit into your life?
