In a picture:
5 yo dropped the dog. Thankfully 5 yo boy is only 3 feet tall so the drop was less than 2 feet, yet the dog yelped and limped for a bit. Littlest cried and then snuggled on the sofa in regretful misery only to be joined by the very dog he had just dropped.
Trying to imagine a cat doing that....
nope, can't picture it.
Forgiveness is a canine strength.
