We have a little "wander off" Yorkie. The two times she has snuck out she has been returned by her PetHub tag. Back in June, Daisy Mae snuck out the back door when no one was looking. Luckily, she got home that same day thanks to PetHub!  Again this week, our Daisy Mae practiced her Houdini skills once again and this time...we figured out her trick!  She won't be able to get the back door opened again. PetHub is by far the best money I have ever spent. The staff at PetHub have been VERY responsive and always follow up with a call to make sure our escape-ee is fine.
