In areas of armed conflict, service dogs can be used to inspect and scour the area in order to detect hiding people, to guard objects, during detours and patrols, in ambushes – to detect people in a timely manner.
Avoiding harassment with service dogs, what to do to knock a dog off the track, substances for temporary or complete incapacitation of service dogs.
The success of dogs is greatly influenced by meteorological and natural factors. Service dogs show the best results in light breezes at speeds of up to 1 m / s. With increasing wind speed, dog performance decreases.
But the greatest difficulty for the search is the complete absence of wind – calm. In this case, the smell is kept on the surface and “sticks” to the place of its exit. The dog manages to take it only with a thorough search after prolonged sniffing of each meter of the area under examination.
The dependence of the correct actions of the service dogs on the wind speed at the ground.
Near each towering wall or large block swirls of the air flow occur, in which even a strong smell, like with no wind, “sticks” to the surface, which also complicates the search. If the wanted object is on the surface, air turbulence does not allow its smell to spread around.
They kind of wrap it around, forming an “air bag”. It is in such bags that you should, as far as possible, arrange resting places for people, if there is an assumption that service dogs will be used for your capture.
Airflow Turbulets Example.
When searching in the mountains, the results of dogs compared to their work in the valleys and at the foot of the mountains are markedly reduced. With increasing relative humidity, dog performance improves. At low humidity, the mucous membrane of the dogs nasal cavity dries out, which negatively affects the work of dogs.
Long rain washes away the smells of traces, while at the same time with drizzling rain the range of smelling increases. Heavy rain, even brief rain, dramatically reduces the likelihood of detection by dogs. Especially low results of dogs on the trail in a thunderstorm.
Dependence of correct actions of service dogs on precipitation.
Solar radiation has a significant influence on the work of search dogs. The best performance of their work – up to 97% – in cloudy weather, when the influence of sunlight is weakened. And vice versa, in sunny weather, when the radiation balance is elevated, service-search dogs correctly identify less than half of the tracks.
With an increase in the temperature of the surface of the soil and air, the performance of dogs decreases. In areas with hot climates, intense heat quickly exhausts the dog and contributes to the disappearance of the smell of the track. And in areas with sandy and solonchak soil, fine sand and dust may enter the dog’s upper respiratory tract, which reduces the effectiveness of its work.
The effectiveness of the work of dogs is affected by the time of day. As can be seen from the table below, search dogs make the most mistakes in the daytime – from 11 a.m. to 4 p.m..
The dependence of the correct actions of the service dogs on the time of day.
Summarizing the above data, we can conclude:
The stronger the wind, the worse the performance of search dogs.
Searching dogs work worse in the mountains than on the plains.
Service dogs the better they work on the track, the higher the air humidity, drizzling rain is especially beneficial for their work.
Heavy rain and especially thunderstorms significantly degrade dog performance.
High soil and air temperatures also reduce dog performance.
The search dogs show the highest results at night. The worst – in the daytime, especially between 11 and 16 hours.
What to do to knock a search dog off the track.
To knock a dog off the track, you can make 2-3 loops on the route of movement as a group. The radius of the loop should be 150-200 meters. The dog in this case will walk in figure eight. It well knocks down water movement, for example, by a stream. Try to walk so that the direction of the wind is away from the dog. Traveling in the wind is always preferable..
Possible route of the movement of the group during its pursuit with service dogs.
If possible, the places of turns and the intersection of tracks (when, for example, loops are made) should be treated with various substances that have persistent unpleasant odors that would irritate the upper respiratory tract of dogs. These smells will force you to refuse to work on the trail..
If there is a suspicion that pursuit with dogs is possible, then the treatment of their tracks with such substances must be done regularly, at all stages of the group’s movement. Traces need to be carefully handled at rest stops.
For temporary or complete incapacitation of service dogs of pursuers, the following substances can be used:
Boric acid, potassium permanganate.
Naphthalene, potassium nitrate, vitriol.
Arsenic, strychnine, carbolic acid.
Chloric lime, lysol, analgin, sulfadimezin and sulfadimethoxine, streptocide, sleeping pills.
Mustard Powder, Pepper, Tobacco.
Gasoline, kerosene, contents of smoke bombs and tear bombs.
When using these tools should take into account the weather. When wet, for example, pepper or tobacco will not give the desired effect. At the same time, bleach and gasoline do not completely lose their properties when moistened. Therefore, try to maintain the maximum possible distance from pursuers with service dogs. The best helpers in this matter are physical training and ingenuity..
