Are dogs luxury?

It happened again today,i was walking with my dogs and stumbled across on one of my neighbours and after short random chit-chat the usual questions that i get started..."Why do i have two dogs?!","Aren't they expensive to feed?","Do i plan to keep both of them?" and such.I am used to these kind of questions,becuase most of time they enter on left ear and exit trough right lol.But what thicks me off are stupid comments that go behind my back,one time i found out that my fiancee's friend asked her:"Why do i treat them and refer to them as they are humans?" (i don't say this is always good thing,but that will be other topic) because all she sees in them are just four legged things that drool (yes,things,many people see dogs as things here),another one said that to keep a dog is "Luxury",i mean first of all...dogs,wheter you have them simply as your best friends and companions or you breed them professionaly to be champs are everything but not expansive unlike some other intrests/hobies people have...and second I for one can say that noone,not my parents,not my fiancee,nor my best friends gave me so much unquestionable and pure love...and we do say that you can't put a price on a love,am i right?
