Unlike service animals, HUD does not require any special training for ESAs. However, we strongly encourage you to make sure your pet understands basic commands, behaves well in a public setting and is trained for traveling if you chose to take it on a flight. The more prepared they are, the less stressful it is for you.
Airlines will revoke the privilege to travel with your ESA if your pet has shown aggression to flight staff, yourself or other passengers on a previous occasion.
Landlords can deny the accommodation or ultimately file for an eviction if the emotional assistance animal is particularly disruptive, or the tenant fails to take proper measures to ensure that the animal does not bother other tenants.
Both you and your furry friend are going to have a much easier time of it if your best friend is well socialized and well-behaved in public. This way, you can enjoy the privileges of being able to take your ESA with you wherever you go.
