I hate hate hate when someone asks me that and I get asked that a lot! Some people just have no manners ... Once someone came up to me and said is it true those dogs are really expensive? how much did you pay for that one?? I was shocked and so peeved off that he treated my dog as if he was just a thing with no other than money value..I just looked at him and told him: expensive? well, if you have to ask you probably can't afford him .... I was feeling brave that day and it felt good, but I usually ignore those people and walk away as if I didn't understand or didn't hear the question, because I am really scared of those who steal them... that's always in my head and I'm very wary.
When someone "nicer" comes to me and asks I usually start talking about vet bills and this and that and don't really give a number. I always say find a good breeder and ask them..... oh BTW @JAKEISGREAT I also got asked once if Ulysses was a pitbull, I was like what? a pitbull? well, oh yeah of course he is! the noisy couple just walked away as if they had seen a ghost
