Q. I have a foster that had his second injections for heartworms. Now he is sometimes gagging. Is this normal or should I take him to the vet? Thank y

A. gagging is one of the possible signs of heart failure or heartworm infestation. Sometimes the treatment also makes the dog worst while the worms are dying and blocking the blood vessels connected to the heart, which can be the reason for the symptoms. I advise you go to your vet to get him checked, there are some additional medication that can be given to support this problem.

A. Most dogs go through a certain amount of coughing and/or gagging after heartworm treatment. This can start at any time. It is caused by dying and dissolving heartworms being passed through the blood and lungs. If it becomes excessive, see your vet.
