There are a few explanations about why dogs can prefer yellow bowls. One of them is associated with the characteristics of the vision of these animals. They can distinguish yellow and blue tones. They see green and red colors as yellow tones. Therefore, this color can be very attractive to them.
Furthermore, according to Aninders of Bhadra, who pioneered a new study, the choice of yellow dogs may be in contact with evolutionary adaptation. In India, turmeric is widely used in different dishes and may include waste remains on the streets. As a result, yellow color for dogs can simply become a food -related signal.
Another interesting hypothesis is that it can be subconsciously associated in dogs with yellow blood and meat. After all, they see red and pink – like yellow tones.
