Yesterday we went to the park and a 6 month old pup ran up to my dog to play. As the owner was calling the dog I stopped walking so I didn't make the pup follow my dog further away from its owner.
When it became obvious that the pup was utterly ignoring its owner I made my dog sit at my feet in the hope that the pup would then do as it was told. It didn't (I had to catch the pup and put it on my lead in the end) but my dog sat there almost perfectly!
I am so so proud of her. It is hard to stay in a sit when it would be more fun to play but she did it!
