Asthma and respiratory medications for pets vary in the ways they work, but they all have a goal of making it easier for your pet to breathe. Some are steroids that help reduce inflammation, including inflammation in the lungs. These medications can also be used to treat a variety of other conditions including skin allergies. Other medications work by opening up airways to make it easier for your pet to breathe. Some focus mainly on treating coughs and throat irritation that can happen due to allergies and bronchitis. Certain medications don’t work well for pets with certain conditions, like high blood pressure and diabetes, so make sure to discuss your pet’s entire health history with your vet.
