I have been looking for the "I'm a Doodle (What are you)?" bandanna for months and could not find it anywhere. I just found the bandannas online last week and ordered one.
If anyone is interested, the site that sells the bandannas is on etsy.com. It's called GlamourDogBoutique. I just received the bandanna yesterday and it's so cute. Sophie is min goldendoodle (19 lbs) and I ordered the Large size and it fits perfectly.
The shop is going to close on July 26th - January 2014, so if you are interested, please order one soon.
I'm attaching a picture of Sophie in her hot pink bandanna. :)
