Thankfully , traffic started moving and I got to the Vet . Carried Stan in to the clinic , because he was working too hard to breath to walk . They were wonderful ; took him right in and started treating him . I do n't know what they gave him , probably some Racemic epinephrine to reduce the tracheal swelling ( at least that is what we 'd do for humans ) , but after a few minutes he started breathing better , they said .
According to the above context, answer the following question.
Why were they stuck in traffic ?


To get treatment for their animal .
