Neutering and Behavior |
Ok, we know smaller dogs live longer
than big dogs. but why is that? Usually bigger animals live longer
than smaller ones,due to their metabolism. Why when it comes to
dogs it's the opposite?
What a good surprise seeing a brazilian around here!
I am not a vet or a zoologist so cannot answer rigidly your question. But just for the pleasure to satisfy you i went to look at Encyclopaedia Britannica that has a table comparing different (maximum) longevity for animals in captivity.
It seems that are not a direct relation between size and longevity.
Grizzly bear: 31 years
squirrel : 15
dog: 34 (!!!)
box turtle: 123
giant tortoise: 177
Hope somone else gives you a more precise answer.
Thanks for asking NEWTON!
