But I definitely won't be dog sitting any more.
Not in a bad way for you but this made me laugh!
I own a pet sitting company and I take care of pets in their own homes. There is NO WAY I would ever bring in a dog into my own home, minus my "niece" (Boxer) who I have known since she was a year old (she is now 8). I know sitters who do bring in their clients dogs and these are dogs they know but yet I have never heard anyone say that all went perfectly well. Something always happens!!
Glad this ordeal is over for you and that she is back with her owner. I am sure she feels better being home in her normal surroundings.
