Fritz with Dad and my sister's dog Taffy on a recent visit.Fritz seems to be saying" What are you doing in my house?"Taffy is all set for St Patrick's Day in her green scarf which my sister calls her jewelry.Fritz stays pretty much out of her way.Last night,Taffy was here as my sister and husband were out visiting friends.Fritz first went to the window and then saw kids and barked,then dad had me bring him in to him on the bed while Taffy was down on the couch snoozing all fours in the air.My brother-in-law came to ger her and got downstairs without her hearing and he was standing over her and Taffy still didn't know he was there.When shedid,she barked and her bark sounds similar to a seal bark.Fritz is now under the couch,tail sticking out of it.
