The best way to stop a dog’s addiction to coffee is to teach it not to drink it, according to experts.
But this doesn’t mean a dog should stop drinking coffee, says one of the authors of a new study, which looked at how to teach a dog to drink coffee and what its role is in the human body.
Dr Sarah Pemberton of University College London said: ‘The most common response by owners is to say ‘it’s OK to drink, I just think its bad for you’.”‘
It’s not really about giving the dog a drink, it’s about teaching it how to think about what a cup of coffee is and why they might drink it and how to avoid it.’
Dr Pemberland is the author of the book, ‘Your Dog’s Coffee Addiction: How to Stop Your Dog’s Drinking Coffee’, and her study is published in the latest issue of the journal Current Biology.
The study found that dogs that learned to associate a drink with the taste of coffee were less likely to drink than those that did not.’
We find that the reward associated with a coffee-associated reward system is not associated with an increase in salivary caffeine levels, and it is likely to be linked with the reward for the reward system in humans,’ she said.’
So it is not really a way of teaching a dog how to drink.’
In fact, it is actually detrimental to the development of the reward pathway in humans.’
The research involved more than 1,000 dogs and showed that if they learned that a drink was associated with the ‘sweet taste’ of coffee, it increased their likelihood of drinking coffee in the future.’
It is important to recognise that when you teach a reward system that’s used in humans, you can’t just expect the dog to learn it without context,’ Dr Pemberdale said.
‘The dogs should understand that it is a reward, so the context is a lot more important than the amount of the cue.’
You can train your dog not to eat anything that smells like coffee and not to use a hot pot or to use ice, but you can also teach it how a cup tastes.”
You’ve got to teach them the difference between the taste and the texture, and the consistency of a cup.’
Dr Richard Saffold of the University of Bristol, who was not involved in the study, said:’There is no evidence that dogs learn to associate the taste or texture of a drink to food with the amount or the quality of the food, so this doesn, in fact, mean that they learn not to associate that with food.’
The study has shown that when dogs associate the smell of coffee with food, they are more likely to eat it and they are less likely in a food challenge environment to refuse food.’
Dr Saffolds said dogs were particularly susceptible to the ‘food-scent-reward-system’ model, which is often linked to anxiety and stress.’
I think the biggest issue with food reward systems is they are built to be in the presence of stimuli that they can’t see, so when they have food they are in the vicinity of food,’ he said.
But the study also showed that there was a link between the type of reward the dog was trained to associate with the cup and how well it performed in tasks.’
If the reward was an ice treat, it had a higher likelihood of rewarding than a hot cup, and when it was a reward associated in a context that it was not in, it was more likely of rewarding in a different way,’ Dr Safflands said.
‘It seems to suggest that when a reward is associated with something, it can change the way the reward is processed, but it is still based on the sensory information that the dog is being trained to get out of it.’
These things are important, but there are no direct links between the reward and how it’s received.’
