Started giving her TUSSIGON.. and it helps.. problem is that when the prrescription ran out, the coughing started again which means it may be that I have to give it to her forever... It is a big expensive.

Anyone know of any other place to purchase Tussigon other than a Vet's office?

Do not know of Children's Robussin would work or not...... Norm
If your dog has an enlarged heart then it should be on medications such as enalapril which help reduce the work load on the heart. Sedating the cough doesn't help the heart. Presumably one could purchase Tussigon online, but you would still need a Vet's prescription to fax in. Again that drug isn't going to do much to help the underlying heart condition.

Get a referral to a doggy specialist.
