I am still seeking for words in Indo-European languages based on the following roots: *ekwo- (horse), *kwon- (dog), *owi- (sheep), *gwou- (cow) and *su- (pig). Would someone please be so kind to fill the following leaks?
 
Hittite: *ekwo-, *kwon-, *owi-, *gwou-, *su-.
Tocharian B: *kwon-.
Old Irish: *su-.
Lithuanian: *su-.
Old Church Slavonic: *kwon-, *gwou-, *ekwo-.
Albanian: *ekwo-, *kwon-, *owi-, *gwou-, *su-.
Armenian: *ekwo-, *su-.
Gothic: *gwou-, *ekwo-, *su-.
 
Are there Old High German, Old English or Old Saxon words based on the root *ekw-?

Is there in any modern Germanic language (except for English "ewe" and Dutch "ooi") a word based on the root *owi-?
 
Can someone give me some additional information about one of these Indo-European roots?
