With their floppy ears, oversized paws and those eyes that make you melt, there's much to love about puppies. Then they grow up.

Luckily, there's PuppySwap, the world's first puppy subscription service, which lets you trade in your grown dog for another fuzzy ball of puppy fluff.

Choose from trending or top-rated breeds and have a new four-legged best friend delivered right to your doorstep.

Don't think a puppy-swapping company is such a great idea? Does it make you feel queasy? That's the point.

PuppySwap is part of new advertising campaign by the Toronto Humane Society (THS) meant to raise awareness about the high rates of pet abandonment.

More than 180,000 animals are surrendered to Canadian shelters each year, according to the THS, and 40 percent don't leave the system alive.

In the United States, 7.6 million cats and dogs enter shelters annually and 2.7 million of them are euthanized, according to the American Society for the Prevention of Cruelty to Animals.

The majority of animals surrendered to shelters are fairly young. According to a study by the National Council on Pet Population Study and Policy, 48 percent of cats and 40 percent of dogs are between 5 months and 3 years of age when they're relinquished.

Makyla Deleo, manager of media relations and event logistics for THS, says some pet owners simply aren't in it for the long haul and age can be a factor in the decision to give up an animal.

"There were the people who surrendered an older animal, and the next sentence is, 'Do you have any kittens up for adoption?'" she told the Toronto Star.

PuppySwap at first appears to be a legitimate business, but when you click to sign up for the service, you get this message: PuppySwap isn’t real. Unfortunately, pet abandonment is.

Of course, not everyone realizes that PuppySwap is a hoax. A video promoting the phony service has gone viral, amassing numerous comments from angry animal lovers. You can watch the video below.
