what you say is use for medical reasons and not athletic purposes while the vet says that everything is ok
not everything, the lungs and the heart. he might still have some problem with the airways or slime which makes him cough sometimes. could be something allergic.
After the first time you use it the effect minimizes, personnal experience that is.
true, i read its prescribed for horses with astma for 14 days, after this the effect minimizes.
Another lighter option is aerolin (salbutamol).
for what purposes?
For anabolic/anticatabolic effects if you are vto use drugs obviously there are much better options.
sure thing, i believe people use it for more air on dogs.
Another bronchodilutor, natural remedy, is a mint tea.
have you tried this on dogs? i dont think its something bronchial though. his lung photo's were fine. think he might do fine with something that widers the airways and deals with the slime. clenbuterol should give results if thats the problem.
