In one adorable video, she pushes Freddy in a toy car.
Freddy climbed in and waited patiently until Lizzy jumped up on the back and pushed him forward.
He’s just 15 weeks old so he has a lot to learn from his five-year-old big sister.Owner Jenny Williams, from Melbourne, Australia, said: ‘This is just a part of our usual training as we like to perform tricks.
‘This was more about teaching Freddy to sit and wait, more than Lizzy pushing.
‘I love seeing my dogs putting smiles on people’s faces.’
Lizzy’s other tricks include pulling Freddy in a toy wagon and she can even ride a scooter.
She’s also learnt to put three paws on a skateboard and use the fourth to move herself along.
Put a ball in your dog's food bowl if he or she eats too fast. They be forced to move the ball around to get to all the food.
What a smart doggo.
Jenny also captures Lizzy in a range of costumes that she wears for her job.
She’s dressed up as Dr Barks, with a white coat and stethoscope, as well as wearing a mane to turn herself into a lion.Jenny posts about Lizzy, Freddy and Harry’s adventures on her Instagram @liz_the_lab.
