Hi Gary, its been a long time :)  yes, I did switch to Tibetans, not bc I don't love Filas, I absolutely still do, bc our lifestyle has changed quite a bit, so not able to have one. We bought an abandoned campground in Southern Missouri, decided to fix it up and open it, so hard to have such a staunch protective breed with lots of strangers around, the Tibetans while still quite protective, are a bit more relaxed, and do over time accept new people :) The litter I bred is actually 3/4 Tibetan and 1/4 English Shepherd, they are still protective over family and home, and great with livestock, the English Shepherd is all of those qualities, but does make friends a bit easier, adds a bit more agility, and helps cut out the health issues common with the purebreds.
