Ok thanks
When we go bikejoring he does not pull me constantly he just walks infront, I bike myself he just helps, he's not strong enough to be able to pull me.
The harness I have for him does not put the weight on his legs, he doesn't get more weight on his legs bikejoring with me then he gets just walking, also I dont bike fast just slow when we bikejore.
I'm just walking him these days, nothing else, and sometimes in the evening we go jogging but I jog really slow so he doesn't run.
He's on pain relievers right now that he gets twice a day and just gets walking or jogging nothing else, and he's on food now that helps him loose weight (royal canin obesity) , when he's in the right weight he goes to LP surgery on 1 foot.
