yesterday my Volka almost 6 months (94 lbs) met for the first time my friend s adult 2 years caucasian ovcharka a monster of almost 170 lbs. however, This particular CO is very good with people but has a serious problem with other dogs. I was extremely nervous at first as they approached but my friend sensed that his dog is ok with Volka and soon they were wrestling on the street like crazy and playing. people gathered around them to watch and to take videos lol. it was hilarious to see them wrestle using their front legs to hold on each other's neck. then when they got tired they just layed down next to each other rubbing their heads together!!! i was nervous all the way and i am not sure how i could put Volka in such a risky situation but my friend kept assuring me that they are ok...i guess Volka was not afraid, and the other dog could tell that Volka was not intimidated so he just accepted him as a friend. Volka even tried to hop him few times lol
