  1. My wife and I recently traveled with Allegiant. In the future, we plan on travelling with you again, and we may also bring along our dog. I see the requirements to bring a dog on board. However, on several occasions I noticed dogs being taken on and from the ship on leash and not in a carrier. If not in a carrier, are there any special requirements or limitations?

  2. I am bringing my dog, a Yorkie , 10 lbs in the cabin for the first time. She is my Emotional support . I am worried there will be an issue from all i have read lately. I have a doctor’s note. I will also bring carrier but i need to pet her so i stay calm. Also, is she considered my free carryon if I am bringing her in the cabin? Or can i bring a free backpack? Does need a heath certificate? If so, when does it have to be dated?
