I agree -- great thread. I relate to many of the posts.
Here are some of mine:
1. Brushing a tiny dog's teeth twice a day.
2. Home cooking dog meals
3. Wearing a front pack carrier daily. It's like a kangaroo pouch, and Tatiana is in it, sticking her head out.
4. Paying for the pet fees for airline flights, i.e. flying with my dog. Also, her travel luggage is BIGGER than mine. She has more belongings that I do.

5. I clean my floors more often because I think it's more sanitary for Tatiana. She's tiny and close to the ground, so I want the floors clean.
The list goes on, but I'll stop here.
