:rofl: I seriously started looking on eBay for a "dog purse" after reading your post, which is another thing I swore I'd never do.
My "attachment parented homeschooled" dog is a hopelessly oversized Chi at this point but still "premie sized" if not "micro-premie sized" and fits in an old infant pouch sling under a pullover. If I was fifteen years younger, I'd just look pregnant.
On the trail, when people see me at a distance and then look up as i come close, they frequently laugh when Laurel pokes her head out or say, "I thought that was a (real) baby!" to which I smile and reply, "She is! She's just a puppy. She is X weeks old and she will get bigger. She is a Chihuahua mix and she wants to make friends, she just doesn't always know how yet."
We have two dog slings because why not! They only have to be strong enough to hold a small dog, not a large toddler, so they don't cost much money to make and I don't mind waiting for the lowest priced one to come from China or Hong Kong. One of them is actually useful as a pattern, even though it holds her way too low as it is, and it showed me how to attach a safety tether to the old baby slings I made years ago and the new doggie slings I'll make in future years.
The other is ridiculous, even though it looked quite nice in the photo.
It cost me about as much as a ticket to a standup comedy show.
