can fit into oven or not? 
and also, if the dog will kill rats.. if it does, it helps if
you're suicidal 
but seriously, before even making plans to get a dog, go read up
books about care for dogs, what types of breeds are suitable for
your home, the space and all that... how much exercise is necessary
to keep the dog healthy and happy... what are the typical illnesses
which the breed is prone to... all that...
go to the library and read up..
but before you go there, google some facts to narrow down your
selection first...
