Spoiler Alert! Answer Below! Spoiler Alert! Answer Below!
Rover had white hair, Fido was yellow, and Spot was brown.
How do you know this? Just follow the logic...
#1 We know that Rover passed his biscuits to the dog with brown hair so Rover couldn't be brown. You also know that Rover had biscuits.
#2 We know that Spot passed his bones to the dog that passed his treats to the dog with white hair. So Spot couldn't be white. You also know that Spot had bones.
#3 If Rover had biscuits, and Spot had bones, you know that Fido must have had the cookies. The dog with yellow hair passed away cookies so you know Fido is yellow.
#4 Now... If you know that Rover isn't brown, and also couldn't be yellow (since Fido is), he must be white.
#5 If you know that Fido is yellow, and Rover is white, then Spot must be brown (since that's the only color left).
So... what about all the other information? For example the details telling us the dogs each passed their cookies to the dog on the left, that one dog didn't get a bone, etc. That's just extra info. We didn't need it to solve the problem.
