Hi there, I have several dog carriers and also have from KB the alex and the alexa, , I honestly love the Alexa ( my favor one) , is more light and the two large pockets are better
that way you don't have to keep looking on what pocket you put what
now the alex is very trendy and stylish lol
here is a thread that I post with tons of pictures, by the way I think the the small size is right for you.
ps: about the sturdy they both about the same
Hope this help somebody, detail review of this two, kwigy bo bags, lots of pictures - YorkieTalk.com Forums - Yorkshire Terrier Community
