They locate survivors in collapsed buildings, track down fugitives, foil drugs and explosives smugglers and help control rowdy crowds. All in exchange for food and lodging — and an occasional pat on the head.
But when retirement time comes, state care ends for the dogs and horses that serve in Poland's Police, Border Guard and Fire Service. They are given away, with no safeguards for their future welfare.
Following appeals from concerned service members, the Interior Ministry has proposed new legislation that would give these animals an official status, and paid retirement to help cover the often-costly care bills their new owners face.
Interior Minister Mariusz Kaminski described the draft law as a "moral obligation" that should get unanimous backing when presented in Parliament for approval later this year.
"More than one human life has been saved, more than one dangerous criminal caught thanks to the animals in service," he said in February.
The new law would affect about 1,200 dogs and more than 60 horses currently in service.
Each year, about 10% of the animals are retired, according to the Interior Ministry. Most of the dogs are German or Belgian shepherds.
Pawel Kuchnio, handler of Warsaw police sniffer dog Orbita, says retired dogs almost always require expensive medical care, to deal with complaints such as strained hind joints.
The pension money "will certainly be a great help and will make things easier," he said.
The bill would confirm the unwritten rule that the animals' handlers have priority in keeping them before they're offered up for adoption.
But more importantly, it would extend state responsibility for the animals into their retirement time and secure financial support for the owners.
Slawomir Walkowiak, 50, a former police officer caring for retired service dogs and horses at Poland's only dedicated shelter, named The Veterans' Corner, says regular state payments would ease concern over bills that reach into thousands of zlotys [dollars] monthly.
The privately run, farm-like shelter in Gierlatowo, west-central Poland, houses 10 dogs, and five retired police horses in a spacious paddock.
The oldest horse there, Hipol, is in his late 20s and almost blind. Walkowiak says he would have a slim chance of surviving at a regular stable.
Walkowiak says many service dogs end up chained to posts or being given unsuitable tasks, as people think they would make good guardians for farms or other properties. This isn't always the case.
"The dog may suddenly remember that it was trained to bite and it will start biting, and when left alone at home it may demolish the couch because it needs to have something in its mouth," Walkowiak said.
In Warsaw, mounted police officer Dariusz Malkowski says he would have to pay the stabling fees for his 13-year-old black gelding, Rywal, if he were to keep him after retirement.
A stall near Warsaw can cost some 2,500 zlotys ($650) a month. The average pre-tax monthly salary in Poland is some 5,500 zlotys ($1,400).
On patrol with Malkowski was Sgt. Katarzyna Kuczynska, riding 13-year-old Romeo II, or Romek, who can identify Kuczynska by her voice.
"These animals have worked for the state, they have done their jobs well and they should be entitled to health care and proper retirement — on green pastures in the case of horses," Kuczynska said.
