The US locations of IKEA are not considered very pet-friendly according to their pet policies on bringing dogs into their stores. The only exception is for bringing in service dogs, which emotional support dogs do not qualify as.

The store wants to provide as many people as possible with a safe and pleasant environment, which is why its policy has remained restrictive. It also maintains the policy to adhere to the FDA guidelines of being a food service establishment.
