As far as getting help here/online, I think your best bet is to get some pictures of Rudy posted. (here or anywhere else) Imagine trying to sell a house or a car just by describing it, you could do it, but it's a lot harder than if you had a picture.
Also, there are multiple vizsla rescue people in the Southwest, a few of whom I've traded emails with before, here is some additional contact info:
Trischa Fleisher (Arizona)
480-348-0324
[email protected]
Rita Prindle (Colorado/Wyoming)
[email protected]
Alyssa McCluskey (Colorade/Wyoming)
[email protected]
Wendy Russell (New England)
[email protected]
Wendy Russell is someone I've spoken with many times, as she's from my area, since she is the regional coordinator for New England and the very worst she will most likely have direct contact information for other coordinators. Even though Charli Stokes is no longer the New Mexico rep, there has to be someone replacing her.
Let me know if you're still having trouble and I'll make some calls for you. And again, post some photos!
