Wow, these are huge!  We have fairly large dogs (English and American Bulldogs), so I bought the largest size possible.  I wish I would have looked at the dimensions more closely.  The dogs will certainly have plenty of room.  Most crates are not nearly this large.  These crates are very lightweight and portable.  They go together quickly and easily, and they fold up nicely for storage.  I wish I would have ordered a size smaller, but I am not going to bother to return/exchange them.  I'd rather have the crates be too large than too small.  The pad is very thin, so we will probably add a thicker pad or additional blankets.  Good value for the price.
