I have a King Charles, she is VERY active. I lead a very active lifestyle, we walk 3/4 time in the week extensively in the forest (around 2 hours) and I also take her with me on runs 3 times a week (45 min run) we have gradually built up to this level over the sat two years. Our usual ‘big’ walk is is a 40 min walk (just under 4K) - some days I have been taking my bike for this route, it’s all grass and she runs through the vineyard without a lead. I drive slow and of course she has no lead so can choose the pace, however, she runs ahead of me (as in, I’m never in front) she is free to run as slow as I cycle which is a fast walk for her at best. She does however seem to choose to run and i worry it’s too much for her? We stop regularly to greet other dogs and she doesn’t give me the impression that it’s too much but I worry for the long term impacts and because I don’t usually see other people biking with a small dog. Should I do this? I only do it because on the days I don’t run, I notice that our usual 40 min walk + the 25 min mini route is not enough and she still has loads of energy .. any advice ?
