I am so glad to hear that Roxie is feeling better, Elyse.  And what do you know, my theory was kind of right about her mammary engorgement.  I must be learning something correctly. 
 
And congrats to you on your Biewer boy; I just posted on your other thread.  Does he have a name yet?  These little dogs (yorkies & biewers) are addictive, aren't they?
