The vowel litter

Since I've had a fair number of litters of seven, I was stumped for a theme.  At first I thought this theme would be boring, but as it turns out there was a bit of controversy over W.  Who knew?  Cathy McKeown (the sire's owner) taught grade school for 25 years and insisted that W is not a vowel, but that's what I was taught in the olden days. <LOL>  Yes, it's somewhat controversial now, like the Oxford comma, but it was in the list of vowels at one time.  So the pups are Abby, Emma, Ivan, Odin, Uma, Wade and Yuri.  I post who's who later.
