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...
