The only dog encounter I remember was a shepard dog with a flock and its shephard. Nothing threatening that I can remember. Though I would agree that this route goes through pretty parts of Galicia, I didn’t find it to be very different from the scenery or ambiente on the “regular” primitivo. But I admit that on my first day, I was not on the Verde from Lugo to Santa Eulalia because I missed the turnoff. So I can’t report on either the first half of the first day on the Verde on the Santa Eulalia variant, or on the non-Santa Eulalia variant, both of which end in Friol. And then for the last stretch of the Santa Eulalia variant, which was where I met the shephard and his dog, I was steered to walk on the side of the untraveled road rather than take the more direct downhill path. According to the shephard, it was filled with “maleza” and not good for walking. So who knows what I missed.
Friol is a small town, and the pensión there seems to stay afload with a small stream of workers who board there during the week as well as a few pilgrims.
The second day starts off through some nice wooded areas, but it does join up with the regular norte about 8 km (?) outside Sobrado, and most of that is alongside a road on pavement.
I would not say dogs are a big issue at all on this route. And for me, the highlight of Santa Eulalia (a Roman crypt/temple/spa - ??? - no one knows) is well worth it, whether you go on the Verde or stay on the Primitivo.
p.s. As between the pensión in Friol or the lovely albergue in Ferreira, I think Ferreira is a much nicer option, so what I will do on my next Primitivo,
, is what I did on my first Primitivo. Walk from Lugo to Ferreira with a detour to Santa Eulalia.
