In the middle of a military base outside Mexico City, an army colonel runs what he calls a kindergarten for dogs.
Puppies that one day will become rescue dogs, or sniffer dogs for drugs or explosives, get their basic training here, at Mexico’s Army and Air Force Canine Production Center. The puppies are born and spend their first four months at the facility, before being sent to military units around the country for more specialized training.
Founded in 1998, the center has in the past produced breeds such as German Shepherds and Rottweilers.
Now, it exclusively breeds Belgian Malinois — about 300 of them a year.
“It’s a very intelligent dog, it’s a dog with a lot of hardiness, very resistant to diseases,” said Col. Alejandro Camacho Ibarra, a veterinarian and the center’s director. It is the Mexican military’s only such production facility, and Camacho said it may be the largest in Latin America.
The mainly green-and-white, one-story buildings look like any others at the military camp in the State of Mexico, near Mexico City. But the difference here is in the sounds that fill the air: high-pitch barking from dozens of puppies scattered through its maternities and training camps.
Precautions here are strict because of a recent canine parvovirus outbreak that sickened some of the puppies. Visitors are disinfected with a spray, and must step into a watery solution to clean shoe soles. Only military personnel can touch the puppies. If you want to get close, you need to wear scrubs, shoe protectors and a mask, but you still cannot hold or pet the animals.
The training starts early in life, about a month after birth once the weaning process finishes. And everything is taught as a game.
“We start playing with the dog,” Camacho said. The idea is to draw them to items that trainers call “attractors” — like a ball or a rag — and puppies are challenged to catch them. “Every time it holds his prey, it’s rewarded, congratulated, and it learns to go after that prey, after that attractor,” Camacho added.
Unlike in civilian life, where puppies often get food treats, in the military the only prize for a job well done is a caress and some praise.
In one section of the camp, there’s a trail with obstacles including rocks, a tunnel, a section of empty plastic bottles to clamber over, a ladder and tires.
A soldier beckons the little dogs with a rag they must capture. The brown puppies with black snouts begin running through the trail, jumping over the rocks and crossing the obstacles. One takes the lead and the second struggles to cross over the plastic bottles, but also finishes. Both go to bite the rag the soldier holds.
“Very, very good, sons! Very good, boys,” he repeats while dragging the puppies as they maintain their grasp on the rag for several moments.
Camacho explains that the puppies are known by a number until they are three months old, when they are given a proper name. Each year, the center gives names according to a single letter of the alphabet. In 2023, that letter is “F.”
Febo, Frodo, Fósil, Forraje and Fido are some of this year’s names.
The basic training ends when the puppies are 4 months old. Then, they move to other military units to become specialists in detection of drugs or explosive, in search and rescue or in protection and security.
The current government of Mexico’s President Andrés Manuel López Obrador has relied heavily on the armed forces for various initiatives, from public safety to the building of airports and a tourist train line. And K-9 units have been a key element of some of the military’s activities, like the detection of drugs.
Col. Camacho said that some dogs born at the center have been trained to detect fentanyl, a synthetic opioid trafficked by Mexican cartels that has been blamed for about 70,000 overdose deaths per year in the United States.
That kind of specialized training happens elsewhere, but the colonel says it builds on his center’s basic training by using “attractor” objects but having them impregnated with the scent of what the dogs need to track, such as a drug.
Dogs retire from their military service after eight years, Camacho says.
Many of the dogs have become unsung heroes of missions in Mexico and abroad. Occasionally they become publicly known, like a German Shepherd named Proteo who was part of a rescue team sent in February to Turkey after a 7.8-magnitude earthquake that killed more than 40,000 people.
Proteo died during the search for survivors of the quake. A statue of him now stands at the center.
Another dog that made headlines in Mexico and abroad was a yellow Labrador retriever rescue dog named Frida. The Navy dog gained fame in the days following Mexico’s Sept. 19, 2017, earthquake that left more than 300 dead in the capital. She retired in 2019 and died in 2022.
Col. Camacho said that the dogs have a symbiotic relationship with their handlers during their working life in the military.
“The dog uses us to survive, but we also use the dog to do a job,” he said. “So it’s a coordinated work where we both get a benefit.”
Are playful dogs smarter? Study finds link between learning and romping
Canine eggheads enjoy playing with toys and retrieving objects.
“Gifted” dogs, who have a rare talent for learning lots of words for objects easily, also turn out to be more playful than other dogs, a new study finds.
Prior research in humans has shown a link between playfulness and problem-solving abilities, so animal behavior researchers from Eötvös Loránd University in Budapest, Hungary, wondered if the same was true for rollicking pups.
What is a gifted dog? In the new study, it was Border collies who had proven in prior research that they were able to learn as many as 12 new words per week and then retain them for months.
To take a closer look at the possible association between giftedness and playfulness in dogs, Claudia Fugazza, a researcher in the university’s department of ethology (the study of animal behavior), and her colleagues asked the owners of 165 Border collies to fill out dog personality questionnaires. Twenty-one of the dogs were gifted and the other 114 were just randomly selected with no testing for word learning ability.
The surveys assessed the personality of the animals in five categories:
- Fearfulness, including fear of people, nonsocial fear, fear of dogs, fear of handling.
- Aggression toward people, including general aggression and aggression in certain situations.
- Activity/Excitability, including excitability, playfulness, active engagement and companionability.
- Responsiveness, such as trainability and controllability.
- Aggression toward animals, including aggression toward dogs, prey drive and dominance over other dogs.
For the evaluation of playfulness the owners were asked to rate their dogs in three areas:
- Dog gets bored in play quickly.
- Dog enjoys playing with toys.
- Dog retrieves objects, such as balls, toys and sticks.
The researchers focused solely on Border collies because earlier experiments found that the breed is more likely to be good at learning new words compared to others.
After collecting the survey responses, the researchers then compared the responses from owners of gifted dogs to those from the owners of dogs who had not been identified as gifted.
Playfulness was the only personality trait that was consistently different between the two groups.
It’s not clear from the study whether it’s the playfulness that helps the dogs learn more words, or whether the extra playful ones ended up with more opportunities to learn, said Fugazza, the study’s lead author, said in an email. That’s because gifted dogs tend to learn words for objects when their owners are playing with them.
Are playful dogs smarter?
Not exactly.
“Intelligence is the result of diverse cognitive traits that allow individuals to flexibly solve different types of problems,” Fugazza explained. “Giftedness refers to an extremely good capacity in the case of a specific skill.”
So, maybe gifted dogs are like people who score high on the verbal part of the SATs.
If your pup doesn’t learn words easily, it doesn’t mean it’s a dumb dog. Adam Boyko, an expert in canine genomics, reassures owners that canine intelligence is more than that.
“Both dogs and wolves are playful when they are puppies, but dogs really evolved to living in the human environment and to responding to social cues,” said Boyko, a specialist in the genetics of behavior and an associate professor at the Cornell University College of Veterinary Medicine. “It’s not surprising that the more playful ones exhibit better learning in the domain of learning human words. And it’s not surprising that Border collies, who are bred to respond to human cues, show the propensity to learn words more than other breeds.”
Other breeds of dogs might show intelligence in other ways, Boyko said. For example, wolves are very intelligent although they don’t typically pick up on human cues.
“But they can figure out how to escape,” said Boyko. “Where dogs would look for a person to help, wolves would see how humans did a latch and lock and then the wolves would do it themselves to get out.”
Boyko would like to take the study a step further and look at the genetics of the gifted dogs.
“This is a tantalizing correlation that might be meaningful if you are trying to build better service dogs,” he said.
One thing that can’t be determined from the study is whether the playfulness trait spurred owners to interact more with their dogs and thus teach them more words, said Dr. Nicholas Dodman, a professor emeritus at the Cummings School of Veterinary Medicine at Tufts University, CEO and president of the Center for Canine Behavior Studies and the author of “Pets on the Couch: Neurotic Dogs, Compulsive Cats, Anxious Birds and the New Science of Animal Psychiatry.”
Dodman said the study is interesting but needs to be replicated in a larger number of dogs.
“I would also like to see it done in a different breed,” he said.
The new findings might help people who want to buy or adopt a puppy. It suggests that playfulness might be a good attribute to consider.
“The playful ones might be more likely to interact with a person, assimilate words more easily and be more intelligent,” said Dodman.
