Carolyn Warmm shared video of her two miniature schnauzers at their home in Richmond Hill, Ontario.
It shows Molly the dog desperately trying to make a great escape by climbing over a pet gate. That's when Marco sees his sister struggling and offers a boost.
In the video, Marco can be seen using his paws to nudge his sister over the barrier.
Warmm says Molly was eager to get over the gate after she spotted a treat.
The adorable duo is the definition of partners in crime.
"Perfect performance of what "Teamwork" means," posted Warmm on Facebook.
