Placental mammals give birth to live young, and they descended from a common ancestor scientists simply call the "boreoeutherian ancestor." The creature scurried about the woodlands of Asia more than 70 million years ago.
They're both members of order Carnivora:
"Carnivorans apparently evolved in North America out of members of the family Miacidae (miacids) about 42 million years ago. They soon split into cat-like and dog-like forms (Feliformia and Caniformia)."

Dogs and insects both have apendages used for moving around, observing this similarity people use the same name to deceive all of them, legs. However to be homologous they must have been inherited by a shares ancestor (common ancestor). Going back in time from the dogs this is an ancestral creature earlier than the earliest vertabrates, before the bony fishes. Considering this it is easy to imagine these distantly related organisms (dogs and fish) did not both inherit the characteristic of having legs from a common ancestor. Therefor legs of dogs and insects are analogous, not homologous.

Isn't a male meerkat called a dog since the meerkat shares a common ancestor with the domestic dogs and the wild cats? Dogs, cats, bears, hyenas and mongooses, including the meerkat share a common ancestor: the extinct miacis.
All dogs, the families and the like, have a common ancestor. Their kind is very different to cats, elephants and fruits.
Dogs and wolves have a more recent common ancestor.
Yes, but so are cats. Cats and dogs are.
Crocodiles and birds share a common ancestor. This can be seen by comparing the internal anatomy of the two. Dogs and Dolphins also have a common ancestor. Their skeletons again are both distinctly mammillian. The ancestor of dogs and dolphins and the ancestor of birds and crocodiles will again share a common ancestor, but you will need to go much further back. I am not sure of the timescales but we are talking tens to hundreds of million years.
