Everytime I re-read the poem while catching up on
posts, I get a different meaning from it.

I think part of the poem (2nd paragraph) can also
mean that dogs can adjust also to our well meaning
mistakes in understanding him/her as a dog, and also
can overlook our mistakes in training, etc.. They love
us anyway !!!

Animals are a great gift to us , and they can teach us
so much. Liz.
