Hi,
I took Mim's to a BBQ Sat and they had a 10-12 ft high deck with part of it not fenced a very small area UNDER an attached bench.

Mim's was playing with other dogs very well, then she was not to be found

.
I looked and there she was on the ground she leaped from that height to the ground with out hurting herself but

there is no fear in this dog what am I to do???

I am now keeping her on a lead even when just sitting. I am very afraid for this dog she is now leaping from our sunroom to the ground our deck is not done yet.

PLEASE give me advise on this . She is my first dog ever and I don't want to lose her.
