Dogs in IKEA bags? What? Why are people walking their dogs in IKEA bags? In some cities (New York City for example) it’s prohibited to take your dog for a subway ride unless it fits in a bag: “No person may bring any animal on or into any conveyance or facility unless enclosed in a container.” However the rules doesn’t say anything about the size of the animal, and as you can see from this gallery, some people got really creative in order to avoid a fine. If you want to join this unusual trend, but don’t have an IKEA store nearby, you can purchase IKEA bags on Amazon.
