How do I get all dogs that are available for adoption?

Is it using a specific path in the GET request, such as

https://api.rescuegroups.org/v5/public/animals/search/available/dogs/

Or is it by using a specific body in the request like

{
    "data": {
        "filters": [
            {
                "fieldName": "statuses.name",
                "operation": "equals",
                "criteria": "Available"
            },
            {
                "fieldName": "species.singular",
                "operation": "equals",
                "criteria": "Dog"
            }            
        ]
    }
}

Or is it by searching by a specific "statuses" id? If the last, which status means "available to be adopted"? The docs are a bit lacking.
