Abstract
In Poland and other countries, the two breeds that are most commonly trained for police
operations are the German Shepherd (GS) and the Belgian Shepherd Malinois (BSM). The purchase,
training and maintenance of police dogs are very expensive. Appropriate preselection can lower those
costs. Therefore, the aim of the study was to compare GS and BSM dogs based on their performance
in obedience, obstacle, defense and tracking tests. The study was performed on 222 dogs which
participated in patrol-tracking training, patrol training and tracking training at the Kennel of the
Police Training Center in Sułkowice. In many exercises: stay in obedience, stair climbing, balance
beam, wooden wall and an obstacle course in obstacle completion, pursuit with a muzzle, pursuit
without a muzzle and guarding detainees in defense, as well as field search, indoor search and
vocalization in tracking, BSM were scored significantly better than GS.

Abstrakt
W Polsce i na świecie dwiema najczęściej szkolonymi rasami na psy patrolowo-tropiące, patrol-
owe i tropiące są owczarki niemieckie (GS) oraz owczarki belgijskie malinois (BSM). Zakup, szkolenie
oraz utrzymanie psów policyjnych jest bardzo drogie. Odpowiednia preselekcja zwierząt może obniżyć
te koszty. Celem pracy było porównanie GS i BSM oparte na wynikach zwierząt w testach
posłuszeństwa, pokonywaniu toru przeszkód, obronie i tropieniu. Badaniami objęto 222 psy, które
uczestniczyły w kursach na psa patrolowo-tropiącego, patrolowego lub tropiącego odbywających się
w Zakładzie Kynologii Policyjnej Centrum Szkolenia Policji w Sułkowicach. W wielu ćwiczeniach:
zostawanie w posłuszeństwie, schody, kładka, drewniana ściana i grupa przeszkód w pokonywaniu
przeszkód, pościg w kagańcu, pościg bez kagańca i konwojowanie osób w obronie, a także przes-
zukiwanie terenu, przeszukiwanie pomieszczeń i wokalizacja w tropieniu, BSM osiągnęły statystyc-
znie istotnie wyższe wyniki niż GS.
Introduction
In the past, shepherd dogs assisted shepherds in managing a flockor a herd
of animals. Today, shepherd dogs are more often used as defense dogs and
military working dogs (COURREAU and LANGLOIS 2004). In Poland and other
countries, the two breeds that are most commonly trained as operational-
patrol dogs, patrol dogs and tracking dogs for police operations are the German
Shepherd (GS) and the Belgian Shepherd Malinois (BSM). This reflects, in
part, the overal trends in dog breeding in Poland (STRYCHALSKI and GUGOŁEK
2010).Dogs that are crosses between the two breeds or Dutch Shepherds are
far less frequently used in police work (SINN et al. 2010, WALASEK 2012). GS
and the BSM are easy to train, and they are widely available from breeders and
vendors. These breeds are also scent-trained to detect substances such as
narcotics and explosives. However, Labradors, Springer Spaniels, German
Shorthaired Pointers and other hunting breeds are increasingly used in scent
training (WARREN 2013, BRADSHAW 2015).
Dogs have to be properly and regularly trained for top performance. Patrol-
tracking dogs should be trained for both defense and scent detection (track-
ing). Patrol dogs and tracking dogs are trained for the same skills: patrol dogs
are trained for defense, and tracking dogs – for scent detection. They are also
trained for obedience and obstacle completion. The selection of dogs that are
best suited for training, the choice of handlers with the desired qualities and
proper training are essential for the effective performance of police dogs
(BRADSHAW 2015). The purchase, training and maintenance of police dogs are
very expensive. Appropriate preselection can lower those costs.Due to lack of
standardization in tests designed to evaluate dog behavior, scientific knowl-
edge about the behavioral differences between breeds and their predispositions
for specific tasks remains modest (GOODLOE and BORCHELT 1998, MURPHY
1998, DIEDERICH and GIFFROY 2006).
Marlena Lipka et al.452
In view of the above, the aim of the current study was to compare German
Shepherd and Belgian Shepherd Malinoisdogs based on their performance in
obedience, obstacle course, defense and tracking tests.
Materials and Methods
The study was performed on 222 dogs, aged 1 to 2 years,which participated
in patrol-tracking training, patrol training and tracking training (Table 1).
The animals were qualified for training based on the results of tests carried out
by certified evaluators. Training courses were held at the Kennel of the Police
Training Center in Sułkowice in 2014 and 2015. All dogs were obtained from
breeders certified by the Polish Kennel Club (ZKwP), a member of Federation
Cynologique Internationale (FCI), the international federation of kennel clubs.

GS – German Shepherd; BSM – Belgian Shepherd Malinois
Dogs participating in all three courses were evaluated for obedience and
obstacle completion. Obedience tests involved the following exercises: heel-
work (the dog walks close to the handler’s leg), turns (the dog maintains its
position throughout the turn), stand (the dog maintains a standing position),
sit, down, stay (while the handler walks away), recall (the dog is recalled from
a stay position and sits by the handler’s left leg) and stop (while moving). The
obstacle completion test included the following exercises: stair climbing (open-
work stairs – Figure 1), balance beam (trapezoid), tunnel, wooden wall and an
obstacle course (various obstacles arranged in line). Dogs participating in
patrol-tracking training were also evaluated in defense and tracking catego-
ries. The defense test included the following exercises: pursuit with a muzzle,
pursuit without a muzzle, protecting the handler, guarding detainees, assist-
ing in identifying a suspect, assisting in frisking a suspect. The tracking test
included the following exercises: tracking human scent, field search (to locate
a person), indoor search (to locate a person) and vocalization (to indicate that

the searched person has been found). Dogs participating in patrol training did
not perform tracking exercises, whereas dogs participating in tracking training
did not perform defense exercises.

The animals were trained by the same persons. Tests were conducted
under standard conditions by certified examiners from the Kennel of the Police
Training Center in Sułkowice. Examination grades obtained by each dog were
entered into Training Progress Reports. Dogs were evaluated during each of
the 4 training stages. Mean scores were computed for each exercise, and the
results were used to determine mean scores for every training category. Dogs
were evaluated subjectively by examiners, on a scale of 2 to 5 points (2 points
– fail, 5 points – highest grade).
Data were expressed as means ±standard deviation (SD). The results
were processed statistically using the least squares method in the GLM
procedure. The results were compared with the use of the Y

Results
The results scored in obedience tests are presented in Table 2. It should be
noted that BSM received higher grades in all exercises, but significant differen-
ces between the two breeds were determined only in the “stay” exercise
(4.16 ±0.45 BSM vs. 3.96 ±0.50 GS, p= 0.019). BSM also scored higher in the
overall obedience rating, but significant differences were observed only at the
trend level (p= 0.053).

The results of defense tests are presented in Table 4. Overall, BSM scored
4.01 ±0.37 points and GS 3.86 ±0.35 points, and the differences between the
breeds were statistically significant. BSM scored significantly higher in the
following trials: pursuit in a muzzle, pursuit without a muzzle, and guarding
detainees. At the trend level, BSM also scored somewhat higher in protecting
the handler (4.20 ±0.57 BSM vs. 4.01 ±0.61 GS, p= 0.096, statistical trend).
No significant differences between the analyzed breeds werenoted in the
suspect identification test (p= 0.614) or the frisking test (p= 0.209).

human scent tracking, whereas BSM scored significantly more points in field
search (4.15 ±0.49), indoor search (4.22 ±0.47) and vocalization (4.75 ±0.39)
than GS (3.89 ±0.51, 3.90 ±0.55 and 4.06 ±0.52, respectively).
Overall, GS did not outperform BSM in any of the evaluated categories
(obedience, obstacle completion, defense and tracking) or individual
tests/exercises.

Discussion and Conclusions
Empirical research targeting the behavioral characteristics of dog breeds is
generally scarce because comprehensive statistical data are difficult and costly
to collect (WEISS and GREENBERG 1997, MEHRKAM and WYNNE 2014, STRYCHAL-
SKIET al. 2015). For this reason, most studies comparing the trainability of
various dog breeds rely on surveys and other indirect assessment methods
(COREN 1994, HELTON 2010, GARDIA
´NOVA
´et al. 2013). The results of our study
clearly indicate that BSM are more suited for police work as patrol-tracking
dogs, patrol dogs and tracking dogs than GS. BSM scored higher in all
evaluated categories.
In a study by GARDIA
´NOVA
´et al. (2013) who analyzed the results of FCI-IPO
world championships, BSM also outperformed GS. BSM scored a higher
number of points in each evaluated category (obedience, defense and scent
tracking). BSM were more gifted than GS, and the greatest differences
between the two breeds were reported in obedience and defense categories. In
the evaluated years, BSM significantly outperformed GS in the tracking
category only in 2003. The IPO disciplines are similar to police training
categories, but police dogs are additionally required to complete an obstacle
course. Our study revealed that BSM scored highly significantly more points
than GS in obstacle and tracking tests, and significantly more points than GS
in defense tests. Significant differences in obedience scores were not noted
between the analyzed breeds.
According to GARDIA
´NOVA
´et al. (2013), GS respond better toa change of
handler and are more focused on the performed tasks. GS are widely trained
for outdoor activities, services and home tasks. However, BSM are more
enthusiastic workers. They are more active in training, they work harder and
learn faster than GS, which is why they are the preferred breed for sports
training. Therefore, it can be assumed that test scores are largely determined
by BSM’s willingness to work. This trait cannot be measured directly, but our
experience with dogs suggests that BSM are much more willing to work than
GS. However, for a new handler, GS is usually a better choice than BSM
because it has better habits and a more balanced character (GARDIA
´NOVA
´et al.
2013).
Dog breeds differ not only in appearance, but also in working intelligence
and trainability (ROONEY and BRADSHAW 2004). COREN (1994) has developed
the most comprehensive scale for ranking breeds by trainability. In Coren’s
scale, GS rank third, whereas BSM occupy a distant 22
nd
position. GS score top
grades in the first category, and BSM score lowgrades in the second category.
These results indicate that GS are able to comprehend a new command already
after several repetitions (1 to 4), and that they perform a task at first command
The performance ofgerman shepherd... 457
in more than 95% of cases. According to Coren, BSM understand the meaning
of the command after 5 to 15 repetitions, and correctly perform the task at first
command in 85% of cases. Coren’s methodologyhas been debated (COPPINGER
and COPPINGER 2001), but most researchers agree with the ranking positions
occupied by individual breeds (DAVIS and CHEEKE 1998, MIKLÓSI 2009,
STRYCHALSKI et al. 2015). However, Coren’s ranking was first published 20
years ago, and the positions occupied by GS and BSM should be revised due to
evolutionary changes in different breeds and modern training techniques. This
observation is confirmed by the results of the present study. It should also be
noted that the number of GS used by border guards and customs officers in
Germany, the breed’s country of origin, decreased by 70% in just one decade
(GERRITSEN and HAAK 2007).
The results of this study and published data do not indicate that GS is no
longer suitable for police work. According to many authors, GS is a highly
desirable breed for less experienced dog handlers (GERRITSEN and HAAK 2007,
SINN et al. 2010, ALLSOPP 2012, GARDIA
´NOVA
´et al. 2013). Beginners quickly
achieve the desired results, even when they make more training mistakes than
their more experience colleagues. BSM can score higher in tests if they are
handled by more experienced police officers. BSM are more eager to work and
are more impulsive than GS, therefore, more experienced handlers and longer
training are needed to control them. BSM seem to be better suited for police
work if placed under the care of appropriate handlers.
Summarizing results obtained in our study, BSM outperformed GS in
obedience, obstacle, defense and tracking tests.
