Hi there and thank you for using pet coach to address your concern. Coughing can be a symptom caused by many different things. Heart failure, respiratory infections, collapsing trachea, allergies, etc. Can cause coughing. It best to have a veterinarian examine Aurora to rule out different causes. I would consider having chest x-rays done to assess the chest for disease. I hope this helps! Please feel free to contact me with any further questions or concerns that you may have.

    Thanks for using Petco Pet Education Center, formerly Petcoach. I’m sorry to hear Prince isn’t feeling well. I recommend taking him to a vet to find out why he isn’t feeling well because it is hard for me to say why he isn’t eating or drinking. A vet will start with an exam- feel his abdomen for pain and listen to his chest for abnormalities. Sometimes white foam is from coughing. Coughing can cause discomfort in the throat causing pets to not want to eat. The vet may need to take xrays or run blood work to determine what’s going on inside. They may be able to prescribe medications to stop the vomiting and make him comfortable to eat. They can also give fluids to make up for not drinking. Good luck and kisses to Prince!

    Thanks for using Petco Pet Education Center, formerly Petcoach! Coughing can be a sign of many conditions such as pneumonia, bronchitis, heart disease, among many other possibilities. I recommend that you have Panda evaluated by your veterinarian for further assessment and treatment. Likely diagnostics to be performed include thoracic radiographs and bloodwork. Treatment would be dependent on findings. Good luck and have a good day!
