but why would something gain fur or any type of insulation if its cold-blooded?

To not lose the heat it just gained perhaps? With insulation, it would become cold far faster without fur. Fur keeps animals warm by containing the heat so less is radiated, so the same would count for reptiles. |

if it weren't for the fact that the days would be shorter then the nights, it would sort-of, and even then the temp would need to be pretty high |

but the point of an insulator is that it prevents the spread of something. the fur would slow the action of heat coming from the sun into the reptiles body. thats why you see no furry reptiles. you do see furry insects and spiders, but they use it for other stuff |

"what would it take for a dog to develop certain intelligence"?, they have good characteristics, firs they are omnivores, they learn a bit fast and they work in packs.

I have seen a show about dogs and they said that over time with domestication dogs have actually gotten dumber than wolves. Especially in the breeds that don't have to think such as the toy breeds. Its the herding dogs that have to do complex tasks that are the breeds that have retained their wolf-like intelligence. This makes you wonder if we are domesticated ourselves into become dumber than our caveman ancestors. At any rate dogs are already smart, have a complex social structure, have emotions, can do many tasks. I would say really its the limitation of their skulls. With such strong jaws their brain can only get so big. They would have to develop weaker jaws and a larger skull to become more intelligence. However since is un-likely due to its benefits. However humans could breed such a trait into a new breed of "smart dog". But is suspect that with the advancement of computers that dogs will be given brain enhancements and could in theory become sapient. Would dogs still be man's best friend or sniff your crotch if they did? Who knows. But its fun to imagine. |

Well I guess its the same answer as what happened for us humans. Some genetic defect happened where their jaw muscles become smaller and allows for the skull to expand. This would allow their brains to get bigger and in turn have the capacity to become smarter. However they still would not have opposable thumb thumbs so tool making would be rather difficult. If anything they would become like dolphins where they have superior intelligence but no limbs to make tools with. |

Lack of predators and lots of food; or food that's hard to reach at their current height.
