🐾 Let’s talk about reactivity…
There are so many misconceptions around reactive dogs, so we thought we’d answer a few of the questions we hear quite often.
🤔 Why is my dog reactive?
Honestly, there can be so many reasons.
Fear, frustration, excitement, uncertainty, pain, illness, previous experiences or simply finding a situation too overwhelming.
The barking and lunging is the bit we can see. Our job is to work out why it’s happening.
🤔 But surely my dog needs to learn that barking is bad? Why shouldn’t I tell them off?
Because stopping the barking and changing how your dog feels are two very different things.
If your dog is barking because another dog worries them, shouting might stop them in that moment. But they haven’t suddenly stopped worrying about the other dog.
Instead, we can teach them what we’d like them to do.
Look back at us, move away, sniff, disengage, walk past calmly… whatever is appropriate for that particular dog.
Over time, we can also work on changing how they actually feel about the thing they’re reacting to.
🤔 But if I give my dog treats when they’re barking, aren’t I just rewarding the barking and making it worse?
This is a really common worry!
We’re not simply feeding a dog for standing there barking.
We can use food to help create better associations and reward the behaviours we do want — noticing another dog and looking back at us, choosing to move away, checking in, disengaging or remaining calm.
🤔 What if my dog won’t take treats when we’re out?
Firstly, that can actually tell us something.
If your normally food-loving dog suddenly won’t take their favourite treats, they may simply be too worried, excited or overwhelmed to eat.
Sometimes the answer is more distance and an easier situation rather than finding an even tastier sausage!
And food isn’t the only reward.
For some dogs the reward might be moving further away from something, being allowed to sniff, having a favourite toy, getting to chase a ball, praise, affection, being allowed to go and investigate something or simply being given more space.
A reward is whatever your dog finds rewarding.
🤔 So why not just correct the behaviour?
Because we don’t always know what is happening underneath it.
Our own dog, Buttons, is actually a really good example of this.
Buttons has recently started having seizures and we’ve noticed that she can become much more reactive around the time of a seizure.
She’s not suddenly decided to be naughty.
Seizures involve abnormal electrical activity in the brain and dogs can experience behavioural changes before and afterwards while their neurological system is affected and recovering.
Punishing Buttons for reacting at those times wouldn’t help her. If anything, adding more stress when her brain and body are already struggling could make things harder for her.
Buttons is perhaps a more obvious example, but with any dog there can be things going on that we simply can’t see.
🤔 Why would pain or illness make my dog reactive?”
Pain or feeling unwell can lower a dog’s tolerance and also make them more protective of their personal space — if you’re sore, you probably don’t want another dog (or person!) bumping into you.
Research suggests pain may be involved in around a third of behaviour cases, so a sudden change or increase in reactivity is always worth discussing with your vet.
Sometimes what looks like a training problem may have something physical going on underneath. ❤️
🤔 Can reactive dogs actually get better?
Absolutely. ❤️
But “better” won’t necessarily look the same for every dog.
For one dog, success might eventually be happily walking alongside other dogs. For another, it might be calmly watching a dog pass on the other side of the road.
Both are progress.
Our goal isn’t simply to make a dog stop barking.
We want to help them cope better, make better choices and, most importantly, feel better about the world around them.
Because once we understand why a dog is reacting, we can start helping them rather than fighting against them. 🐾
