Get one right away and get her used to it. I have to put mine up because Ahi will want to lie in it all day. When I bring it out she hops right in. From the get go I never played with her while she was in it. So she never makes any noise. We go to every restaurant with her. No one EVER knows. She is quiet and depends on what i'm eating I may give her a treat or two for being such a good girl. Other wise she just takes a nap or chews on her bully stick.
I suggest getting one with sides that don't wilt if you are putting her down and not carrying the whole time. I have both the Kwigy-Bo Alex(Soft) and the Lucy Luxury's Charlie Bag(Stiff sides). We use the Lucy's a lot. Kind of pricey but worth it to me. I want to get another, from the Jaraden SoHo Collection the one that Lil Sis is selling.

It's kind of like getting them used to using a kennel.
