I have asked for crossposting permission from the Vet, who's posts on another list re stroke started me on my researching same in dogs. If, and when, she gives the permission, I'll forward it here. In the meantime, I'll try to find links to some info. Barb Bowes Bo & Chelsea (Pyrs), Flopsy (Pyr Shep) & Machin (Doxie) The more people I meet, the more I like my dog! bamb@monmouth.com
