Summary: Researchers at the Penn Vet Working Dog Center have discovered that teaching dogs to voluntarily dunk their heads in water is the most effective way to rapidly cool them down after exercise, potentially preventing dangerous heat-related illnesses.

As summer temperatures continue to rise, dog owners now have a simple yet innovative technique to keep their furry friends safe from heat-related illnesses. A groundbreaking study published in the Journal of the American Veterinary Medical Association (JAVMA) has found that training dogs to voluntarily submerge their heads in water is the most effective method for rapidly cooling them down after exercise.
The research, conducted at the Penn Vet Working Dog Center at the University of Pennsylvania, compared various cooling methods and discovered that voluntary head dunking not only cooled dogs faster than other techniques but also prevented dangerous post-exercise temperature spikes. This finding could revolutionize how we approach canine heat safety, especially in situations where access to large quantities of water is limited.
The Science Behind Head Dunking
Dr. Cynthia M. Otto, lead author of the study and executive director of the Penn Vet Working Dog Center, explained the significance of their findings: “This study changes our understanding of cooling methods in the dog. During heat stress, blood flow to the head, nose, tongue and ears is increased. Cooling the tissues of the head allows for rapid cooling of the whole body with limited amounts of water. Furthermore, training the dog to participate in the cooling process can enhance not only its safety, but the human animal bond.”
The research emphasizes the critical rule of “Cool first, transport second,” encouraging owners to begin cooling dogs immediately if they show signs of heat stress, before seeking veterinary care. This approach could be lifesaving, as heat-related illness poses a serious risk for dogs, especially during warm weather when they can quickly overheat during activities.
Implementing the Head Dunking Technique
The voluntary head dunking technique uses positive reinforcement training to encourage and reward dogs for dipping their heads into water to retrieve a toy or treat. Clean room temperature water is gradually added until the dog is comfortable immersing its head to retrieve the reward.
This method offers multiple benefits:
- Rapid cooling of the entire body
- Prevention of dangerous post-exercise temperature spikes
- Flushing of the nose and eyes to remove dust and debris
Training time may vary from a few days to several weeks, depending on the individual dog’s comfort level and motivation. However, the potential benefits make it a worthwhile investment for dog owners, especially those who frequently engage in outdoor activities with their pets.
Comparing Cooling Methods
The study evaluated four different cooling protocols:
- Neck chemical ice packs
- Wet (22°C) neck towel
- Wet (22°C) axillae towels
- Voluntary head immersion (“dunking”) into (22°C) water
Among these methods, only the voluntary head dunking technique prevented dangerous post-exercise temperature spikes while also cooling dogs faster than the other methods.
Practical Applications for Dog Owners
As summer continues and many pet owners enjoy outdoor activities with their dogs, this research provides timely and relevant information. Whether for canine athletes, working dogs, or pets enjoying a day at the park, the head dunking method offers a simple way to manage heat stress.
Dog owners should consult with their veterinarians about incorporating these techniques into their pets’ routines. It’s important to note that while this method is effective, it should be used in conjunction with other heat safety measures.
Recognizing Heat Stress in Dogs
Pet owners should be vigilant for signs of heat stress or heat stroke in their animals, which can include:
- Anxiousness
- Excessive panting with easily visible molars
- Drooling, especially thick ropey saliva
- Vomiting or diarrhea
- Abnormal gum and tongue color (dark red)
- Unsteadiness or collapse
If any of these signs are observed, owners should begin cooling efforts immediately and seek emergency veterinary care.
