معنی Going on در جمله‌ی زیر

It means participating in or engaging in an activity, in this case, running.

So, the sentence is telling us that Taz, a good dog, enjoyed running together with Danelle. It suggests that Taz and Danelle had a close bond and often went on runs together, which both Taz and Danelle enjoyed.

The phrase "going on runs" emphasizes the regularity or repetition of the activity. It's not just a one-time thing, but rather an ongoing activity that they both participated in and found enjoyable.

در اینجا going on فعل دو کلمه ای نیست(به معنی ادامه دادن و پیشروی) و صرفاً یک حرف اضافه است:
تاز سگ خوبی بود و از (رفتن به) دویدن به همراه دانل لذت می بُرد.
