Trigger Stacking

Trigger Stacking

Scruffy and his owner are out for a morning walk. They come upon a woman pushing a baby stroller – something that is completely new to Scruffy.  As the stroller passes by, Scruffy’s owner notices that Scruffy is yawning and ducking his head away from the stroller.  He can’t possibly be tired ….

A few blocks later, a loose dog runs out of his yard and starts barking at Scruffy. Scruffy cowers, moves behind his owner and starts licking his lips. The loose dog’s owner calls him away. Since Scruffy didn’t growl or bark at the loose dog, his owner assumes that it wasn’t a big deal. They continue on their walk.  

Trigger Stacking

After work, the owner decides to take Scruffy out for another walk since he has been cooped up in the house all day.   As they walk past the next door neighbor’s house, their old dog walks up to the fence.  Suddenly, Scruffy explodes – barking and lunging at the dog.  The owner is very upset and yells at Scruffy as he drags him away. “What the heck is wrong with you?! You see that dog every day! You never act like that!”

  • Joey had a veterinary appointment first thing in the morning. He doesn’t really like riding in the car, but since he is a little dog, Jane just lifts him up and pops him into the car.  He sat still and pouted all the way to the vet – never giving Jane any eye contact.
  • At the veterinarian’s office, Joey was faced with all of the sites and strong medicinal scents of the receiving area and crouched down in a corner. When they got to the exam room, Joey hid under a chair. He had his ears back and wouldn’t look at Jane.
  • Joey’s vet was booked, so he saw a new vet and vet tech.  He wouldn’t come out from under the chair, so Jane had to reach in and grab him. Since Joey wouldn’t sit still, the vet tech had to restrain him.
  • After a physical exam during which his teeth, ears and eyes were checked and his temperature was taken, Joey got a couple of vaccinations.  
  • While they were in the office, it had started to rain. As Jane and Joey ran across the parking lot to their car, a big dog in another car barked and surprised them both. 
  • On the way home, Jane stopped off at a store. She had to leave Joey in the car – something he hates. But the weather was nice and cool and she just needed a couple of items, so he would be fine.
  • Joey started barking when Jane got out of the car and she could still hear him as she entered the store. When she came out, she could hear Joey barking as she approached the car. He was SO excited to see her. Silly boy, she was only gone for a few minutes.
  • On the way home, a car pulled out in front of Jane, she had to slam on the brakes. Joey slid off the seat, and then decided to just stay curled up on the floor.
  • When Jane and Joey arrived home, Joey walked through a couple of puddles on the way into the house. When they got inside, Jane set her bags down and grabbed a towel. She leaned over and took Joey’s leash off.
  • When she picked up his front paws to dry them off, Joey gave a bit of a growl and lifted his lip, but he does that sometimes so she kept going. When she grabbed his back leg to start drying his paw, Joey growled, spun around and nipped her arm.
  •  When Scruffy yawned as they passed the baby stroller and licked his lips when facing the loose dog, he was trying to tell his owner that he was uncomfortable with the situation.  Be sure that you know how to recognize even the very subtle signs of stress in your dog. My blog, Dog Body Language:  How to Speak Dog, is a great place to start.  If you would like to take a deeper dive, check out my Canine Body Language for Pet Parents webinar.  Norwegian dog trainer, Turid Rugaas, wrote a fantastic book on the subtleties of canine body language – On Talking Terms with Dogs:  Calming Signals , Lili Chin has a very informative little book called Doggie Language that is filled with graphics and Tricia Hollingshead’s Listen to Me is filled with color photos and fantastic information . . .
  • Mediate the intensity of the situation by controlling duration and distance with respect to your dog’s triggers. If you think that your dog might be getting trigger stacked, you can prevent outbursts by maximizing distance from triggers on your walk, go to a quiet place for a sniffari or even skip the walk and do some trick training, nosework or even a scatter feed in the yard instead.
thresholds
  • Keep a journal of events that may be triggering to your dog and mediate the intensity of your dog’s encounters with his triggers in order to prevent over-threshold reactions and trigger stacking.
  • Possible triggering events to be aware of:
    • Children
    • People ringing the doorbell
    • Grooming, nail clipping or other types of husbandry
    • A trip to the vet
    • A new object – a stroller, wheelchair, holiday decoration, etc.
    • A new location 
    • A familiar location that has changed – an empty park may be full of people, a change in season or weather has changed a familiar landscape
    • A car ride
    • Other dogs or people when out on a walk
    • A new pet in the home
    • Visitors in the home
    • Losing a member of the household – moves/is out of town; a pet/person passed away
    • A pet sitter or boarding
    • Any change to his normal routine
    • Pain or illness
    • Time of day – light and shadows can effect visibility
    • Loud noises – construction; thunder; fireworks; car backfiring
  • Don’t push your dog’s boundaries until he is ready.  If he is stressed by an event, take extra care with other possible triggers.   Decrease intensity and duration as much as possible and increase distance as much as possible.  There will be better days for reactivity training.  Right now, your priority is self-care for your dog’s mental health.
  • If you and/or your dog are struggling, contact a certified professional dog trainer whose training philosophy is grounded in positive reinforcement to help.

Dog Body Language: How to Speak Dog

Dog Body Language: How to Speak Dog
Dog Body Language

The truth is … our dogs are speaking and they are begging us to listen to them. In truth, too many of us do not understand the subtle signals that make up dog body language. When we don’t see, or if we choose to ignore, our dogs’ subtle signals, they have no choice but to speak louder through growls, barks, snarls … and even bites.

  • “I get anxious when you restrain me. Please stop hugging me.”
  • “It hurts when you pull on my matted fur. Please stop brushing me.”
  • “Cars are scary. Please stop forcing me to get in.”
  • “My joints hurt. Please stop petting my leg.”
  • “I just want to enjoy my dinner. Please stop sticking your hand in my bowl.”

Never punish your dog for growling.
