Before we go tonight, we want to introduce you to a very special and very good dog in Ukraine.

At this rehabilitation facility in Kiev, some of Ukraine's wounded warriors work hard to learn how to use their new limbs.

If they need inspiration to persevere, they can look to a dog named Lava.

You feel a sense of emotional relief, especially with a dog here on prosthetics, just like us.

It's truly wonderful.

Lava was found near Odessa's railway station after a train had severed his front paws.

Now he uses prosthetic paws.

They're made of titanium, just like amputees' prosthetics.

And like many of the patients, they're integrated with his bones

through an advanced reconstructive surgery procedure called osteo integration.

Wavr's owner is the founder of the rehab center.

It's remarkable that our work inspired the veterinarian, a trauma surgeon, to perform

osteo integration on this dog.

And it succeeded.

They designed and produced titanium implants.

He's a fixture at the center, playing with patients and joining in physiotherapy sessions.

Lava behaves as if his prosthetics were his natural paws.

The most important thing is that the dog has accepted the prosthetics.

He doesn't chew them, he licks them,

treating them as his own paws.

If they felt artificial to him,

he would have chewed them off.
