It seems as though Hot Rod's body and leg hair takes a long time to grow out while his face and tail grow out quickly.  He has thin, soft hair.  I guess this is a silky coat??  Just when his coat was actually feeling a bit fluffy and full, it was time to shave him down for the summer.  

  It took since last year to grow it out. 
Maggie on the other hand has a beautiful fluff coat that grows out much quicker.  I would love to have her grow long but it just gets so hot here in MD and I just think it's so much cooler for them.  Also I think that it's easier to spot any ticks on them being shaved down.
