10/10/2006 I came across these accounts of dogs and wolves in A Journey Through Spain in the Years 1786 and 1787 by Joseph Townsend. I assume the tiger is a lynx.
Piedrafita [in Jaca], a little village containing forty six houses is fed by a little valley and surrounded on every side by mountains. The shepherd dogs are large, well qualified to engage the wolves, which are here in great abundance. They wear a spiked collar to protect the neck, and to prevent the wolf from fixing on that mortal part. …..[Pyrenees] On the mountains I am told, are not only wolves, but bears and a species of the tiger; all of which, in the winter are exceedingly ferocious. From the dread of these, the shepherds constantly drive their flocks of sheep and goats into the villages by night, and when they are feeding on the mountains they are attended by strong dogs with spiked collars…. [Pyrenees] All the dogs in the little villages through which we pass have spiked collars . These are absolutely needful because wolves abound in these regions. In winter they become ravenous and bold, but in the summer they commit frequent ravages among the flocks by night if either the shepherd or the flock are sleeping soundly. [Somiedo]
And here is one of the spiked collars, a carlanca. More here. (Fapas)
