After searching for some on etsy, I came across Catey Blue. Their bow tie collars are extremely adorable and affordable compared to other doggie bow tie collar sellers (yes, this exists!). And on top of all this, their customer service is great! The collar I received was a little too big for a Medium so they sent a new smaller one the very next day!
Here are some of my favorites sold at their shop:
And of course, something pretty for the ladies too!
