From the 40 sequences notated using EWMN, four distinct cat-egories of rolling over were discernible. Given that few people are able to read EWMN scores, the types of rollovers are described in written form with photographs of sequences illustrating the main types. While several contexts were identified in which rolling over occurred, in none of the 40 interactions subjected to EWMN analysis, did any dog rollover in a manner that is consistent with submission. That is, no dog rolled over in response to an approach or aggressive action by the partner and did not remain passive in its back. A quantitative evaluation of all instances of rolling over was conducted to ascertain whether such submissive rollovers were ever present (see Section 3.3).
