My dog has tracheal collapse since his young age, now limps and walks on 3 legs, can't walk down the balcony steps to the yard anymore, so I have to take him down so he can relive himself... I have to consider his quality of life here if his limping doesn't improve, his meds include glucosamine.. will make a vid on him soon..
