Marleys walk yesterday

so Marley finally got the chance to play with a puppy around his age and size gorgeous French bulldog 5 months. As I said before I thought Marley was being aggressive towards another family dog Ben, but I watched him play yesterday and I'm not convinced it is just puppy play Marley jumped growled arms going up and down rolling trying to talk whilst chewing grass face planting the floor with his but sky high haha, he was very funny to watch and wasn't nasty once! Was quite hard to get them both to stop playing haha, hope I seen them again for some more play time. Also I'm using a training lead nw can any1 give me some tips on using one?

Use the training line and commands as much as possible his recall will improve the more time you practice

Yh he comes every time till he sees a person then he bolts, when he runs it to it full length he gets jolted backwards then, and I don't want him getting hurt, so think I'll keep it to a certain length, he prefers it tho got abit more freedom
