You want the sole focus to be on the color if that's what you are interested in. Your description certainly explains why virtually all of the dogs I see at the local animal shelter never bother to sheild their eyes from the sun - they will happily catch a treat thrown towards them in direct sunlight. As for the laser trick; perhaps your dog is an anomaly or he sees the laser dot as a 'vivid black' for want of a better description. Either way, there are too many variables - some cats will chase a light, some won't.
Also, since red is interpreted as a 'danger' sign by humans, and it's well established that dog behaviour is much learned from humans it's no wonder they frequently ignore red toys, even if they do appear a different color. One more point: I'd be interested to find out the spectrum limits of dogs' vision copared to ours. I suspect they can see well beyond humans' and into the infra-red wavelengths. I have always wondered how they can say any animal see's this way or that way. How do you know? Interesting article though. They do tests.
Also examining the structure of the eyes would yeild clues as to the way the eye sees.

Cones, rod etc. Then they compare that to the structure of a human eye. It's not perfect mind you there is still the matter of the brain processing the data from the eyes but once again examining the structure of the brain and tests done on it can yield the clues needed to assemble a picture of how the animal sees things. I have a year old Shitzu and according tpo the topic on color and the spectrum illustrated for dogs, I certainly cannot agree that dogs only see certain clors. I have a set of balls exactly the same of different colors, yellow, red, orange and neon pink. When tossing the yellow ball to her which she returns and then throwing the pink color she certainly indicates that it is not the one she returned.
I she is asked to fetch the red one with them all lying in the same vicinity she heads directly for the red one. You say 'red' and think of the colour red. Your dog doesn't. He can't see the colour red as you see it. He doesn't have the correct cells in his eye.
Dog Poop Color #3: Black/Maroon Poop
You have taught him the sound 'red' means 'that one'. He sees a nearly black ball. You see a red one. A green laser pointer is very cool and convenient, I have bought 3 pens and recommended laser pointer to my friends. Thanks for taking the time to discuss this, I feel strongly about it and love learning more on dogs colorblindness.

Regards, dog shop. Further to Christina's Question of "Why? And I believe that most dogs can easily pick out different coloured toys because they have learnt to associate the name with the smell of that particular toy. The yellow ball that they play with most will smell completely different to the neon pink one that they don't. You see this effect when buying a new replacement toy sometimes. The new one might be identical except for a little less wear, but they won't touch it. They only play with the old one. I know this because I run a pet shop and sell lots of toys and get lots of feedback from customers.
If I notice a toy is becoming a favourite I rush out and buy another identical one. I swap them around regularly. That way favourite toys last twice as long, or I have another if one gets lost. I have a hunting dog,and he is very interested in laser pointer spot. However, I always feel that my dog can recognize things by their smell.
Actually, both color and smell can effect a dog. My dog Zenna is a chichuahua, I bought her 2 dog toys similar to each other with long stems coming up, one is a orange cat and one is a red bull. She has accetped the red bull over the orange cat. If dogs cannot see red, how come she loves the red bull? Color is human perception of spectral radiation. There is no animal, fish or insect which is endowed with human tri-chroma capabilities and hence no animal, etc. I understand what you are saying when you contend that dog and undoubtedly other creatures "see" color because most will see portions of the electromagnetic spectrum and react appropriately.
But labeling such as color vision is incorrect popular "science" because most any scientific text on color and vision will define color as a process that is created in human eyes and is sorted out in human brains. For color to be seen, there needs to be an object which reflects wavelengths that stimulate the cones in human eyes, when, of course, the object is illuminated by a light source. The human eyes criterion is the key to the definition of color vision.
Blue, I guess would be the best colour for her ball. Thank you for your information. Michael Melbourne, Australia. I read this article and thought OK cool so that's how it is.

If when you examine him and detect that he has lost a lot of weight , has become lethargic, has a bad mood or is presenting a combination of many diseases, beware, because he may be suffering from a skin cancer, fairly common when we speak of malignant tumors. In summary: the depigmentation of the nose of the dogs has many causes.
