My dog has had a cough for a month, some nasal discharge and now ALT is 520s after doxy

Thanks for reaching out with your concern. Coughing, nasal discharge, and an elevated ALT level in dogs can indeed be worrisome, so let's explore what might be happening with your furry friend.



A persistent cough and nasal discharge suggest respiratory involvement, and they could be symptoms of an infection, like kennel cough, or more chronic issues such as allergies or even more serious conditions like heart disease. The elevated ALT, a liver enzyme, might indicate that the liver is stressed, potentially due to medication, an underlying infection, or another condition affecting the liver directly.



Doxycycline, often used to treat bacterial infections, could either be addressing a bacterial cause or contributing to liver stress depending on your dog’s overall health and response to the medication.



At home, ensure your pet stays hydrated, as fluids can help with both respiratory and liver health. Try to minimize your dog’s exposure to irritants such as smoke or strong fragrances. Monitor his energy level, appetite, and any changes in the color of his gums, as these can indicate if the situation is worsening.



It's crucial to keep an eye out for signs like difficulty breathing, vomiting, jaundice, or a significant drop in energy level. If you notice any of these, seek veterinary care immediately.
