Based on the experience and the benefits of participation in ERASMUS + programme (the State Border Guard Service of Lithuania (SBGS) dog handlers and the Border Guard School (BGS) students do not have much opportunities to participate in similar fields of activity in order to improve their international competencies, except when they participate in FRONTEX activities) we want to continue and develop a successful project activities . SBGS Dog Handlers and BGS have defined one general and main objective of the project - to improve the competences of BGS studnets and dog handlers in ensuring border control. Based on this, we have foreseen two target groups in this project - SBGS dog handlers and BGS students. During the project, one mobility visit in Estonian Police and Border Guard Board structural units for the BGS students target group was carried out (5 participant, 12 days long) and four mobility visits for the SBGS Dog Handlers target group (2 Dog Handlers with service dogs per visit, the duration of each visit is 12 days). All in all 5 BGS students and 8 SBGS Dog Handlers has improve border control competencies. As separate goals for the above mentioned target groups were set: For the dog handlers – strengthening of cooperation between border guard services in the field of dog handling at the international level, improving of dog handlers’ training programs, enhancing of dog handlers’ competences as well as skills and professional efficiency in use of service dogs in EU external border control (to prevent illegal border crossings and smuggling of excise goods, explosives, narcotic materials across the EU external border). For the BGS students: 1. to get acquainted with the specifics of the operation of the border guard service structural unit of the partner country, ensuring the protection of the EU external border and the legal regime, the specifics of the organization and implementation of border control; 2. gaining international practical experience in border surveillance (patrols in various patrol units) and border checks (travel, personal and vehicle documents examination); 3. during the internship, prepare a creative task (presentation, writing, etc., assigned or chosen before leaving for mobility); 4. to improve knowledge of English in quantitative and qualitative terms. The participants were enabled to carry out service together with their Estonian counterparts (dog handlers patrolling at the state border with service dogs, BGS cadets patrols in various types of patrols, work at the border crossing point) by implementing foreseen and approved activities in tripartite contracts. Through its activities, the SBGS has directly contributed to the implementation of the FRONTEX Regulation, i.e. the ability of border guards of EU Member States to work together, with a common understanding and application of legislation in border control procedures. High-quality staff ensures proper protection not only of the EU's external borders but also of its internal borders. The dog handlers gained experience in the use and training of service dogs for the protection of the state border and shared best practice to the colleagues of the Police and Border Guard Service of the Republic of Estonia. The project was beneficial for the partners as they also took over the best practices from the project participants. The BGS cadets also improved their border control competences, gained practical and teamwork experience in an international environment. Moreover, foreign language competences were improved of all persons involved in the project. Finally, we are delighted that during the mobility visits, participants twice contributed to saving civil lives (finding a lost elderly woman and timely called help for a man who was spotted outside the partner's structural unit and had a serious medical condition). Partners were very grateful to SBGS and project participants on these specific occasions. +
