My dog is pretty helpful with my writing (I'd include a picture of her but it throws my old computer into a tailspin. She basically looks like a skinny black lab). How my dog helps with my writing:
1. When I've been at my desk too long, she paws at my arm for attention, telling me it's time to let her outside. Or take her for a walk. This forces me to notice I need a break, and possibly some head clearing fresh air.
2. She gives me a warm shoulder to cuddle up to when I'm feeling frustrated and my writing isn't working.
3. When I want to read my story out loud to check the rhythm, I can pretend I'm reading to her. So then it seems like I'm a weirdo that reads to dogs, not a weirdo that reads to nobody. Why aren't the kids around when I need them?
4. If I hide a dog treat inside an old rejection letter, she'll rip it to shreds for me. I haven't actually tried this, but it might be fun.
