The Department of Transportation is proposing an overhaul to the regulations around service animals on flights in the United States, banning all animals except dogs, and no longer forcing airlines to let animals accompany passengers who say they need them just for emotional support, officials said on Wednesday.

The proposed new rules will be open to the public for comments for 60 days, and then the department will analyze the results before it makes a final decision, it said in a media briefing.

In a statement, the department said it “recognizes the integral role” that service animals provide for people with disabilities, but added that the changes could help reduce the likelihood that passengers would be able to “falsely claim their pets are service animals.”

Under the proposal, passengers with physical or psychological disabilities who want to bring a dog into the cabin as a service animal must fill out a federal form attesting that it has been trained to perform tasks that address the disability, the officials said.
