My dog has been hacking and hacking..I took him to the vet and they gave me Amoxicillin. He has been on it for a week and is still coughing. (its not a quick cough but a hacking and then coughs) What else can it be.
He is a small chihuahua about 4 1/2 lbs. I do have 2 other chihuahua's and they are fine.
He plays and eats normal.
This could be tracheitis, upper respiratory infection, collapsing trachea, bronchitis, etc.. You may want to go for a re-check and possibly a chest x-ray. vetcare
