Do you know what to do if a dog becomes aggressive in your consultation room? How can you get yourself, and others, out safely?
I am a Certified Clinical Animal Behaviourist and I’ve been teaching defensive handling to rescues for several years. These ‘safety skills’ can be learned by anybody and can help you prevent and de-escalate canine aggression to turn a dangerous situation into a safer one.
Also known as defensive handling – safety skills are just like ‘defensive driving’ - being proactive, rather than reactive. In a veterinary context, aggression is frequently due to fear, pain or fear of pain (Riemer et al. 2021). When faced with a perceived threat, many animals will choose to move away from the interaction. When the danger is perceived to be too close, and there is no escape route, animals may use forward-moving body language, including aggression, to create space (Panskepp, 1998). An animal’s stress may therefore pose risk to the veterinary team (Nibblett, Ketzis & Grigg, 2015). Safety skills are the way that we reduce this risk, and keep everyone safe.
With known fearful or aggressive cases, information gathering ahead of time is the key to success of the session. By exploring the animal’s history, we can make a plan to mitigate the potential risks. Does the dog have a bite history, and if so, what was the level of injury? What techniques have been tried in the past, for example, does the the dog find it less stressful to be examined on the floor, rather than the table? If there is time to plan ahead of the session, it may be beneficial to:
If the dog has no issues with resources, is not nil by mouth, and has no dietary issues, you may want to consider using a mix of rewards of varying values as this can increase the response rate (Steinman, 1968). The use of toys may also be beneficial as play can improve social cohesion between humans and dogs, increasing their familiarity and reducing agonistic interactions (Sommerville, O’Connor and Asher, 2017). A study by Salomons et al. 2025 also found evidence that play after training helped dogs who were in the early stages of learning new behaviours improve when they revisited the training the next day.
Food enrichment is known to reduce abnormal behaviours (Schipper et al. 2008), so having a practice enrichment or ‘behaviour box’ including ready to go resources, such as lick mats, snuffle mats or Kongs may help more anxious patients. A study by Squair et al. (2023) used Lickimats® as part of low-stress interventions during veterinary visits and they were found to have a greater reduction in stress over time compared to those without interventions.
Reading canine body language can help prevent escalations in behaviour. The following traffic light system is a quick introduction to canine body language:
Doggie Language by Lili Chin is a truly fantastic resource for anyone to learn about dog body language – I recommend it to every client and professional I work with – full of beautifully illustrated cartoons, it’s super easy to flick through and even great for children!
Alongside body language changes, some other indicators that a dog may be reaching their threshold are:
It is important to constantly assess body language and be aware of the subtle, low-level signals that a dog may be feeling uncomfortable. Each dog will have their own unique communication system, based on what has been effective for them in the past. If we ‘listen to the whispers’ in terms of low-level communication, a dog may not feel the need to escalate their behaviour, or ‘shout’ for space - when choices are removed, options become reduced. When proceeding with caution, with ‘amber’ body language, it is important to consider:
If a dog shows ‘red’ body language – stop what you are doing. Leave the environment, if it is safe to do so, and call for support. If a situation is essential but it has been stressful for the dog, it is important to document this information for the future. Information to record includes the events that led to the incident, the body language and behaviour of the dog, what actions were taken and any resulting injury. This helps from a staff safety perspective but also from the dog's - we may need to put some plans in place for future visits to help mitigate any future risk and to help the dog learn alternative coping strategies.
When working with dogs it is important to be mindful of always adopting safe body positions that mean you can get yourself to safety if a dog’s body language changes:
If a dog is displaying body language that makes you feel threatened:
1. Raise the alarm
2. Respond – how you respond will depend on the type of bite:
Snapping bites
Ragging bites
Grabbing and crushing bites
3. Report
When reporting, be sure to include the level of bite - the Dunbar Dog Bite Scale is a widely recognised scale.
Every practice will see aggressive dogs from time to time. Many of these dogs are responding to fear, pain, or the fear of pain, and early planning and practice-based interventions can reduce the risk of aggression. Constantly monitoring dog body language and responding appropriately as outlined helps to keep staff, pet owners, and their dogs safe.
