no it's really just about the fact that someone lost a pet he cared for and we're all trying to cheer him up because we're decent people when it comes to that and people had to come in here and be ing s. so naturally they're going to get snapped at or made fun of. |

sorry, you've got that backward. big dogs live longer than little ones. |
i dunno, i would think a quantity of how much they are inbred / purebread would be a more siginificant factor then size.
generally the rule is a slower metabolism the longer the lifespan. generally larger animals have slower metabolisms.
There are exceptions however. Animals that are less preyed on also have a longer life span. Birds and bats for example. This perhaps reveals something about their life history, there is no need to reproduce quickly and use up resources before death. With an extended life, they can take their time with mating growth and diet without the repercussions of predation. |

| well yeah, i just meant in a situation where all things are equal, bigger dogs tend to live longer. |

no variables? wheres the fun in that. Fair enough i will concur. |

btw, i'm giving away a 30 gallon aquarium, tired of that crap too. Just come and pick it up, i'll throw the african fish in the pool and see how long they'll last. |
not very long. even baby sharks die in an hour or two from the chlorine. |

lols. including variables would take me well outside my field of knowledge, which basically starts and ends with “big dogs live longer” :p |

obviously nautral selection is not a factor for domestic dog age so essentially, a smalller breed dog. which its ancestors have a sheltered life expectancy of up to 17 years (gray wolf), may live to be longer.
Just through deductive reasoning i see it as less strain on the physical body. smaller body, less complex system with the majority of geneitcs directing it towards a 17 year lifespan. So essentially you can get a couple of more years by reducing its size.
Generally the rule which applies to smaller animals depicts that these animals have been evolving for thousands of years and generations, with their age and metabolism being correlating factors. A smaller animal is more vulnerable to enemies and thus must hunt quick, eat quick, reproduce quick and die quick. Its energy will be geared towards the first 3 points.
Now lets say you take a grey wolf who has been evolving over thousands of years naturally through the environment. its a genetically clean species which lives up to 10 years in the wild and perhaps 16 or 17 in captivity (where resources are plentiful, no enemies/ injuries and competition etc). You begin to inbreed this species and over several generations lets say 2500 years. The animal still carries most of the genetics of its ancestor (the gray wolf) including an expected lifespan. The dog is more mobile, smaller and less strained to get around. essentially this will be a plus for the animal and perhaps extend its liefspan a bit.
This is my theory on the whole shindig.
Dogs are always exceptions since they are selectively bread. you cannot put them into the context of nature predicting their life cycles as traits will be amplified through forced selection. |
