We have vizslas and only started off running with them at around 12-18 months old.
These were not on roads, we did through fields and on footpaths and then walked when it came to roads.
We are quite cautious about hip dysplasia and joints though, none of ours have ever been allowed upstairs in the house unless invited up for a bath etc
I wouldn’t do 6 months personally, I’d wait until 10 ish minimum and start off small on soft trails
This is just my personal opinion and from having a breed of similar ish build for 12 years. I’d ask the vet next time you go and get their take as well
