My dog is pretty good at finding wounded birds, in fact, if she can't find the the one that is wounded she will find one that isn't wounded, pounce on it, and bring that one back. When we give her the command "Dead Bird" she will deliver a bird one way or another.
Bobeyerite you need to find a snake avoidance class and get him vaccinated. My guy was having a great day a few months ago and his last bird was a snake. Its a terrible situation you don't want to deal with. Also find out where the emergency vet clinic is near you and if they carry the antivenom. Big if.
The vaccine is controversial as to its effectiveness but 3 emergency vets I spoke with say dogs who have been vaccinated do better with treatment. I would call around and form your own opinion. The problem is there are no clinical studies as nobody wants to volunteer their dog for such a thing.
