Hello,
You each have a different motivation while outside. I take my dogs for a run (they are a year old too), every single day. But I only run after they have had a walk to go to the bathroom and investigate their territory. That way we each get our outside time and preferences for being out there out of our system. The other thing that helps is running with someone who’s dog already understands the routine. Let them learn from another dog. And please whatever you do never get upset or frustrated. Your dogs whole life and purpose is you. So be kind and considerate and remember this is your kid so you have to compromise. They will love you more for it and your life together will be happier and easier.
It could be nerves/anxiety… in which case you would have to work to change the behavior and also work on her anxiety. You may want to discuss it with the vet and see if they have any recommendation as they know your pet better than me. I would try to find a good dog behaviorist (your vet may have a recommendation) to help show you the best way to handle this with your dog. Best of luck.
