Don't feel the need to apologise at all! That sounds like a traumatic expeeience.
It's so difficult to keep training, especially when there are so many external factors beyond your control. With Akira I feel like it's a constant battle of 2 steps forward and 1.9 steps back. Progress is so slow, or will sometimes disappear altogether. Two weeks ago when I was at my parents he just took off without warning, and started running down the main road which was terrifying. He got about a mile and I only got him back because a kind stranger stopped and grabbed him.
Feels like we are back to square one, but we aren't, all the training we have done previously is still there, just need to keep reinforcing it. It's tough and tiring though.
