Maybe a tiny trim, like below, but I think your composition as-is works just as well, and an argument could be made that the smaller the dog is in the frame, the more vulnerable it looks.
A difficult subject for me because I'm such a dog lover, and my current companion was rescued from the streets. You've captured an emotional scene for many of us.
Your crop suggestion is not bad! I will definitely take it into consideration before making any prints.
That's sometimes the tricky thing with crop selection... a little trim here or there can shift the emphasis of the image's message as well. A few days away from the image can sometimes help me decide which crop is most effective.
