Which colour of dog stroller suits you and your personality?
And dogs can see some colours too – not just black and white!
In our everyday lives, we are surrounded by colour. The colour of your clothes, home decor and even the colour of your car is chosen by you. Each colour has an individual personal meaning for all of us. Our favourite shades can make us feel a whole lot better when we are feeling down, and cheer us up when the weather outside is pretty grey and miserable.
So what are your favourite colours? Do you have a favourite? Are you pretty passionate about pink? Crazy for anything red? Or are you into the dark mysterious shades of grey, navy or black?
Dog strollers and pet trailers come in an array of colours
You are now able to choose from a whole array of coloured dog strollers available here in the UK. Dog stroller manufacturers put a great deal of thought into these colour choices. Some are vibrant, some are pastel and some are contemporary and subdued. Some bicycle dog trailers are coloured to look good but are also designed to be seen by other road users, especially in low light weather conditions.
Dogs can see some colours, not just in black and white
Many people assume that dogs can only see in monochrome (black and white) and that the choice of what colour dog stroller you buy would have no effect on your dog. But surprisingly, some scientists in Russia recently found out that dogs DO have a limited colour range in their vision! Dogs can use these colours to distinguish between items around them.
A team of researchers from the Laboratory of Sensory Processing at the Russian Academy of Sciences tested the sight of eight dogs of varying sizes and breeds. The aim of this research was to expand on last years findings which was carried out by the University of Washington. Scientist Jay Neitz from the American university carried out experiments on dogs to test whether they could see in colour or not.
He discovered that while human eyes have three ‘cones’ that detect colour and can identify red, blue, green and yellow light; dogs only have two. This means dogs can distinguish blue and yellow, but not red and green. This is the same spectrum seen by humans when they have colourblindness.
Look at the two colour blocks below. On the left is the colour spectrum that humans can see (well humans that are not colourblind). The block on the right is what scientists believe are the spectrum of colours that dogs can see.
How they found out that dogs can see some colours
The Russian scientists therefore printed four pieces of paper in different colours; dark yellow, dark blue, light yellow and light blue. The dark and light hues were used to test the theory that dogs use brightness levels to distinguish between items. In the first test, researchers took a dark yellow and light blue sheet of paper, as well as a dark blue and light yellow combination and put them in front of food bowls placed inside locked boxes. They then unlocked one of the boxes and put the dark yellow piece of paper in front of the box containing a piece of raw meat in each trial.
Each test involved the dogs being allowed to try to open one box before being taken away. It only took three trials for the dogs to learn which colour paper was sat in front of the box containing the raw meat. Once the dogs could identify that a piece of dark yellow paper meant meat was nearby, the researchers wanted to check whether the animals were choosing this paper because of its brightness or its colour.To do this they put the dark blue paper in front of one box and light yellow in front of another. If the dogs chose the dark blue paper, the scientists could rule that the animals were making choices based on brightness.
However, if they chose the light yellow paper, the choices were based on colour. Each dog chose the light yellow paper – meaning they were making choices based on colour – more than 70 per cent of the time. Six out of the eight dogs made the colour choice between 90 and 100 per cent of the time.
In conclusion, the researchers said: ‘We show that for eight previously untrained dogs colour proved to be more informative than brightness when choosing between visual stimuli differing both in brightness and chromaticity. ‘Although brightness could have been used by the dogs in our experiments, it was not. ‘Our results demonstrate that under natural photopic lighting conditions colour information may be predominant even for animals that possess only two spectral types of cone photoreceptors.’
Colours and their meaning
Out of interest we have looked into and researched the science behind some colours. With each colour we have found out some meanings, feelings and emotions that associated with that specific colour. Take a look at what we have found out by reading the chart below!
