My 8-year-old Pom breathes mouth open, sleeps sitting. What's wrong?

Thanks for using Petco Pet Education Center, formerly Petcoach! Some common issues in pugs and other small breed dogs that can result in trouble breathing include heart disease and pneumonia. There are other conditions such as inflammatory and infection diseases that can affect dogs. I highly recommend that you have Leo evaluated by your veterinarian for further assessment and treatment. Likely diagnostics include thoracic radiographs and bloodwork. Good luck and have a good night!

He needs to be examined by a veterinarian right away. Your vet can take an x-ray of his chest to evaluate his lungs and airway. He could have pneumonia, asthma, heart disease, or fluids in his chest. Please call your vet immediately and schedule an appointment.

Thanks for using Petco Pet Education Center, formerly Petcoach! Breathing problems can be a sign of many conditions such as pneumonia, bronchitis, heart disease, among many other possibilities. I recommend that you have Bailey 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 night!

Hi there and thank you for posting on Petco Pet Education Center, formerly Petcoach! Unfortunately, I cannot legally advise on medication or the dosages of medications over the internet. If Boo is coughing and having trouble breathing, he may have an upper respiratory infection or his symptoms may be caused by another medical condition such as feline asthma. Foul smelling saliva can be related to an oral infection such as a tooth infection or can be related to an upper respiratory infection. I would recommend Boo see his primary care veterinarian for an exam to help diagnose Boo's condition so he can receive the most appropriate treatment. Best wishes to you and Boo!

Oh no, poor Ruffus! From your picture, it looks like he is quite ill. I see significant discharge from his eye, and that mucus from his nose is quite thick. He could be suffering from a severe respiratory infection causing his symptoms. If he's breathing through his mouth, then it is likely because he is very congested. Ruffus could also have an eye infection causing the discharge, and any problem with the eye should be considered an emergency because it's such an important and delicate structure. He does need to see a vet immediately for these symptoms so he can be treated. Please take him into an ER vet clinic; if there isn't one in your area, there will be a vet on call for emergencies. The information to reach that vet is found on a clinic's answering machine or website.

An abnormal breathing pattern can be a sign of many conditions such as pneumonia, bronchitis, heart disease, among many other possibilities.

Thank you for submitting your question regarding Xiaozui. I recommend that he sees a veterinarian today. The symptoms you have described are concerning. He could have a respiratory tract infection making him congested with nasal discharge. Perhaps this is making him lethargic. Difficulty breathing though is very worrisome. He needs to be evaluated so treatment can be started to help him feel better. I hope this information helps!
