I love how my golden retriever/chow mix looks when she is wearing a bandana. It just gives her a little additional cute factor, something unique. And that becomes even more unique when the bandanas are something that I hand selected fabrics for and handmade myself.
The reason I don't just cut the fabric into a square with pinking sheers and tie it on is simple. My dog is constantly going in and out of the house, she gets put on a run/line and a regular bandana often gets in the way. Also wears a training collar for walks and traditional bandanas gets in the way of that too because it makes her have 3 items go all the way around her neck. These slip on (to any collar) bandanas stay in place (on the back of her neck) because of the balance of her buckle and ID tags. They make putting on a leash. line, or training collar much easier. They work great for us I hope they will for you as well!
The measurments I used for this bandana are for my 80lb golden/chow mix, but this can easily be made for whatever size dog you need just follow my directions for the correct measurments.
First thing you need to do is measure you dogs collar. I measured the space between where her ID tags hang, all the way around until the buckle, this was 15 inches. Then I measured that her collar has a 1 inch width.
