I have done some TT's with mine outside of my home. The next steps will come after this ridiculous heat in the form of different dogs on strange territory and then hopefully on their home turf. After doing it on strange territory with this breed I am seeing the benefits of doing the same at home. Walking a fine line here, but IMO mastino are more protective at home and I would love to see the differences in the same dogs, 2 tests. :wink:
