Ah! Apologies! I must have missed it in the description. I did manage to lasso the horse a few times but I found it tricky to balance dodging the logs with also playing the mini game to toss the lasso followed by the second minigame to tie it down. On the one hand, two minigames really made me feel like I could've really been wrangling a horse but given that the lasso can miss even if you succeed on the throw, perhaps I would have been a little less frustrated if getting the lasso around the horse was all I had to do. I'm thinking that maybe the solution was to slow the horse with sugar cubes first and then lasso the horse?
