She’s a mixed breed, about 40 lbs. no clue what she is really but we think she has some German Shepherd in her and definitely Bazenji. She loves to run. I have a bike leash and run her. She loves it. I can run her 5 miles and when we get back she still doesn’t lay down.
She is still a youngster, I bet she will end up being one of the best dogs you have ever had. To be able to run her with a bike leash, she has to be well behaved. A 40 lb dog could pull you off balance easily. I am sure you will give her plenty of time to mature.
My own dogs are not perfect but we get along well.
