@Rebecca860 While I can't make any concrete assumptions, it sounds like the guest utilized the "service animal" policy to circumvent extra charges (pet fees). True service dogs are very well behaved and are typically not left alone to run wild/freely in a space that is not their home. While you cannot ask for documentation you are allowed to ask the following:
- Whether the guest requires their service animal because of a disability
- What work or task the service animal has been trained to perform
Additionally, per Airbnb policy
- A guest’s service animal must not be:
- Out of control
- Un-housebroken
- Left alone at the listing without prior approval
- Allowed into areas that are considered unauthorized to the guest
- Allowed in a public space without being harnessed, leashed, or tethered and not under the guest’s control
This guest did not follow policy in place for service animals, which is a violation. Additionally, as with any pet in Airbnb space, there is a reasonable expectation that guest will clean up after their animal. Moving forward, if a guest brings service animals and violates policy and/or is not cleaning up after them message the guest first and let them know of the concern. If they continue to fail to follow the rules you can reach out to Airbnb for support and explore your options such as cancelling, etc
