In this video we were at the dog park. The brindle staff-goldi-mix is Sophies best friend Merle(first dog she met), the only female dog I know who is able to correct Sophie without beeing targeted by barking etc from Sophie. The Rotweiler male is a confident, slow moving stranger we met minutes before, you can see how Sophie has to greet him(licking the muzzles) everytime she comes around him and how she runs hectically between those dogs, and then the stress gets to high and she shows a displacement activity (picking-up a stick, letting it fall, picking it up again and running to Merle to lick her muzzles again. I think in that moment she was really stressed because Merle was highly excited cause of her stick-tick and didnt react to Sophie. Again I m not able to see a sign of fear in Sophie its more pure overhelming excitement, which she isnt able to controll.
