Jan,You are always so clever, M.
the conventional wisdon is they pup should have only enough room to
stand, sit and lay down in the crate. i solved the too-big crate problem
by buying a roll of screen, like you'd use for a window. these days it is
fairly soft and flexible. and cheap at someplace like home depot.
i cut a piece slightly larger than the dimension of the crate and sectioned
off the crate to the size i needed. i secured the screen with those plastic ties
you have to cut off. when i needed to make it a bit larger, i cut off the existing
and repeated the process, installing a new piece of screen farther back in the
same manner. i had all of the plastic ties on facing out of the crate and then i
snipped them off as short as possible w/o undoing them. that way there was
nothing tempting to chew on!
good luck it and i'm glad Sadie is feeling better!
