what type of harness to use with a bike leash attachment to walk dog

hi health for my dog is important and walking him outside is a necessity.   i ll need to use a bike to walk (and trot) my 6 month puppy since i have a personnal walking mobility issue. I look at the springer on amazon and the leash will put tension always on the same side of the dog. I wonder if it is ok to attache the leash to the d ring at the top of the dog harness or if it is better to buy a harness that has dring on the side and why . And what about cliping the leash to the front (Y harness). what are the impact on the health of the dog . And what is safest. if i dont over run him, can using a bike attachement create problem regarding the way he walks (maybe dysplasia)because of pressure coming always from the same side. ( im not talking about risk of him getting into the wheels ) . The thing is that when a normal human walk a dog the tension comes from higher and sometimes walk to the left then to the right of the human but with this bike attachment it will always be from the same side and probably more lively rough leash tension. If you have recommandation of harness for golden retreive for such an activity let me know. Same thing , if you know a device dog bike attachement safer than the one on the picture I am all ears.   thanks

Hello and first can I say that I appreciate the thought and work that you are putting into this issue.  You sound to be a true engineer.  However having seen my fair share of injuries involving dogs being dragged along roads by vehicles (and potentially vice versa) I am concerned.  I wondered whether running your dog alongside a more solid vehicle (four wheels on the ground) might be safer but there is always the concern if you stopping at different rates or heading in different directions in extremis.  However, I hear that it is chronic issues, rather than sudden accidents, that is concerning you in this question so will treat that issue alone / hypothetically.   More to follow

I agree with your assessment that this dogs' joints would not be being loaded evenly in walk, run or trot.  Our understanding of arthritis is changing in that we are now realising that uneven weight-bearing affects the joint on a molecular level over time.  So: arthritis causes uneven loading AND uneven loading causes arthritis.  Running alongside a bike would involve repeated pounding of joints, rather as marathon runners are exposed to, and doing that with even an apparently minor imbalance in muscle loading could frankly be a concern.   If you have the resources, speaking to an expert in arthritis might prove interesting.  However, for me there might be value in looking open spaces (off season beaches depending where you live?)  where you can let your dog run free and channelling this energy into working on the recall.

Hi , Thank for taking time to answer me . Would changing the side where the  bike attachement is fixed (it can operate on both side) one week on the right one week in the left side  etc. grossly nullify the problem from the tension always comming from the side? It feels like i could  a kind of symetry back to the system. -- I will not have the dog run . just 30min walk with 2 x 5 minutes sections at trot speed to spend his energies. I idont have beach close and i cant walk on my feet regularly . The dog has to be exercised so i have to take the lesser bad options. My wheelchair is too slow and sometimes there is to much snow to use the wheelchair at all but the bike with nails is always possible . Would you know any bike attachement that would be better ? thanks!  

HI Anyone could answer?  

Sorry it's late - I've been giving this some thought.  I think in general, that applying a force on both sides would give one side a rest occasionally and therefore reduce the load on that side.  However, it would also potentially increase the load on the opposite side, subjecting it to the same forces.  In an ideal word, my assumption would be that it would be best on the joints if this wasn't happening, but please do get this clarified by an experienced orthopaedic vet.
