Yes, like people, dogs, cats and many other animals, cows can develop asthma. In fact, cows are prone to asthma or allergies at certain times of the year. Signs that your cow may be having trouble breathing due to allergies or asthma include wheezing, dry heaving, or coughing. If you see this in your cow, please call your vet right away. Allergy related symptoms may subside when you remove the cow from his environment. For instance, if your cow is living in the barn with the bales of hay and sawdust pile, move him to a different area away from these items to see if the breathing is better. If the allergies are from something in the air then your vet may prescribe an inhaler similar to what people use. Make sure you talk to your veterinarians Wichita, KS for full operating instructions on the inhaler.
