Pippin absolutely loves his licky mat and the cashew nut butter! He can sometimes get overwhelmed when we go out to new places like cafes and pubs and having the lick mat with us really helps him to calm down and settle and it's great to seem him relaxing. The mat is so easy to take out with me and it sticks to the floor really firmly so it's super secure while he's liking it. Would absolutely recommend to any dog owner!

An essential part of mine and Bruno’s daily routine The Steady Eddie lick mat has been so helpful for Bruno and myself. It’s now a huge part of our daily routine for whenever he’s feeling anxious, such as me leaving the house. I’ve noticed a difference in how relaxed he stays throughout the day, even during stressful situations. It brings so much calm to our home!

My dog absolutely loves this peanut butter! The moment I take the jar out, his tail starts wagging with excitement. The texture is perfect for spreading on lick mats, stuffing into toys, or using as a training reward.

I purchased the Paw by Four Smooth Peanut Butter for dogs for my dog, Rocky, and I couldn't be happier with it.  He absolutely loves the taste and gets so excited when I get the jar out.

Excellent product — my dogs love them and the best is that this has really reduced anxiety when I have to leave them at home for a bit. The suction cups are very helpful for enabling the pad to be fixed on tiles or windows.

100% peanuts and no nasties! Finding a safe peanut butter for dogs can be scary with potential hidden ingredients, but I love this one for Bruno because it doesn’t contain any xylitol. It's literally just peanuts with no nasties in it at all. It’s become a big part of his daily routine spread onto the Paw by Four lick mats. Bruno is obsessed with the taste and I get peace of mind knowing it’s just peanuts.

what if it isn't anxiety?

Not every worrying behaviour is anxiety. Pacing, whining, chewing, following you from room to room can all point to it and sometimes that is the answer.  But pain, boredom, over-excitement, learned habits and some medical conditions, can look almost identical.  But each needs different support.

Our free guide Is It Really Anxiety? helps you tell them apart. It won't diagnose your dog, but it will help you understand what you're seeing so you can talk to your vet.

Common questions

Everything you need to know

You are not overreacting. The fact that you are asking the question at all usually means something has caught your attention — a change in behaviour, a response that feels disproportionate, a level of distress that does not match the situation. 

Anxiety in dogs is not always dramatic. It does not always look like barking, destruction, or visible panic. It can be as quiet as a dog who rarely settles, who follows you from room to room, who startles easily, or who seems to shut down in new environments. The physical signals — yawning, lip licking, whale eye, a tucked tail — are easy to miss if you do not know what you are looking for.

The honest answer is that distinguishing anxiety from normal canine behaviour, from boredom, from a medical issue, or from a personality trait takes a little knowledge. That is exactly what our free guide is designed to help with.

They are related, but they are not the same thing and understanding the difference helps you respond more accurately to what your dog is experiencing.

Fear is a response to something present and specific. A dog who flattens when a truck passes is experiencing fear. The trigger is real, immediate, and identifiable. When the truck is gone, the fear typically subsides.

Stress is a physiological state, it's the body's response to pressure or demand. It can be triggered by fear, but also by physical discomfort, uncertainty, overstimulation, or even excitement. Stress is not always negative, but chronic stress, the kind that never fully resolves, causes real harm over time.

Anxiety is anticipatory. It is distress in the absence of a current threat, a dog who becomes unsettled before you have even picked up your keys, or who cannot relax in a new environment even when nothing is wrong. Anxiety is about what might happen, not what is happening. The difference is important, because it changes both how you understand your dog's behaviour and how you approach helping them

Honestly: weeks to months, depending on the severity of the anxiety, the consistency of the approach and the individual dog. There is no shortcut, and any product or programme that promises rapid transformation is worth approaching with scepticism.

What you may notice relatively quickly — within days to a couple of weeks — is a reduction in the frequency or intensity of individual episodes when a calming tool or environmental change is introduced. That is a real signal. It does not mean the anxiety is resolved, but it means something is shifting.

Deeper change — a lower baseline arousal, reduced reactivity to established triggers, an increased ability to settle — typically takes longer. Three months of consistent effort is a reasonable minimum expectation for meaningful behavioural change in a moderately anxious dog.

The most important thing to track is the change.  A dog who is recovering a little faster after a stressful event, or reacting to slightly fewer triggers than before, is improving even if the improvement is not yet visible in the moments that matter most.

It may be but shutdown is worth understanding as its own thing rather than immediately labelling it as anxiety. A newly rehomed dog who is still, quiet, unresponsive, or disinterested in food, play, or interaction is often not showing anxiety in the active sense. They are showing overwhelm. The nervous system has reached its limit and is protecting itself by switching off.

This is a normal and temporary stress response in many rescue dogs, particularly in the first days and weeks in a new home. The three-week adjustment period you may have heard about is real: the first week is often survival mode, the second week is cautious exploration, and the third week is the beginning of genuine settling. However, some dogs take longer.

The right response to shutdown is space, predictability and patience. Resist the urge to introduce your dog to everyone, take them everywhere, or actively try to bring them out of themselves. Let them set the pace. Provide a safe, quiet space they can retreat to. Keep the environment calm and the routine consistent.

If shutdown persists beyond four to six weeks without any signs of emerging confidence, or if it tips into visible distress — trembling, refusing to eat, inability to settle at all — then it is worth a conversation with your vet.

It is a fair question, and we would rather answer it honestly than dodge it because we sell lick mats.

The evidence for repetitive licking as a calming mechanism is genuine. Licking activates the parasympathetic nervous system, that's the part responsible for rest and recovery, and has been associated with reduced cortisol levels in dogs. The slow, rhythmic nature of licking a textured surface also provides sensory engagement that redirects a dog's attention away from a trigger and toward something manageable. That is not a marketing claim; it is a well-established aspect of canine behaviour science.

What lick mats are not is a cure. They are a tool and are most effective as part of a wider approach to anxiety management, particularly in the moments before or during a known stressor: a car journey, a grooming appointment, the period just before you leave the house. Used consistently and in the right context, they earn their place. Used as a standalone fix for severe anxiety, they will disappoint.

We designed KalmDen as a direct response to Ava's reaction to thunderstorms.  The final design is the culmination of extensive research and several prototypes.  KalmDen won't stop noise entering, sound deprivation in itself can cause stress and anxiety but like its inspiration, the fox den, entering sound will be absorbed and echoes restricted.  The soil walls of a fox den are replaced with dense recycled architectural PET felt, providing an acoustically calmer den-like sanctuary for your dog.
