Well i have noticed that Leo is growing more outwards now rather that upwards looking more bulky very strong boy and a very naughty one yesterday over the park as soon as we pull up in the car he is whining and pushing and jumping like mad with the 2 greyhounds in the back as well its the case of he gets out first!! i get him reasonable calm make him sit and wait then he sees a little dog runnning around off lead that was it barking jumping frothing like mad to get over there i slipped on mud lost my grip and he was gone he isnt at all aggressive just too playful for some dogs he didnt come back on any call lucky enough the lady wasnt scared like some owners she held him till i got over to him she said she was more worried for Leo as her little terrier holds no prisoners if other dogs are too much in this case Leo was too excited and the little one eventually let him know. he has been at gsd training 2 times now and i intend to keep it up he only does it over parks. street walks and other dogs are Ok
