My senior Chihuahua with heart murmur coughs at night, can't sleep.

I would be extremely concerned about her having a cardiac issue. Please take her to your vet so they can check to see if she has a heart murmur as that can lead to heart failure. Coughing is one of the first symptoms. She is the right age and breed for this to be happening. The other likely cause would be a collapsing trachea. So again, please take her to your vet for an exam. Best wishes.

Coughing and not really eating in a dog with a heart murmur(s) could point to congestive heart failure. Please take her to a vet immediately. You cannot wait.

I recommend bringing him to a veterinarian and having them listen to his chest. This may be respiratory or heart related but having a veterinarian auscultate them is the first step. It may require x-rays to determine what it going on also. Thank you for using Petco Pet Education Center, formerly Petcoach.

This could be an upper respiratory infection such as kennel cough , but could also be a sign of heart disease, especially if Chico is an older dog. Another very likely possibility is that Chico has a collapsed trachea. You will need to take Chico to your vet for an exam and x-rays (which will rule out collapsed trachea and lung edema caused by congestive heart failure). Your vet;s exam will also detect any problems with the heart, that may be causing the cough. Please cschedule an appointment with your vet soon.

There is no way of knowing how long this may have been developing but it is quite likely the condition developed in line with the worsening cough and breathless signs. Tracheal disease is common in this breed also and it is not unusual for both conditions to develop in the same dog, weakness and coughing at rest is generally considered indicative of a worsening heart condition which requires ongoing medical management to reduce symptoms and delay progression

Poor guy. Coughing a small breed older dog can be caused by several things including: underlying heart disease, chronic bronchitis, tracheal collapse, or even neoplasia. The first step here would be to get Dino Diaz seen by your vet and have chest x-rays done to help narrow down the possibilities here. Once we have a proper diagnosis, then proper treatment can be recommended to hopefully reduce or even completely resolve the cough. In most cases though, the cough can only be reduced, which helps the pet become more comfortable and have a better quality of life. Schedule an appt with your vet soon. I hope that Dino Diaz does well moving forward and that his cough improves. Best of luck and take care.

Thank you for contacting Petco Pet Education Center, formerly Petcoach with your question about Dino. Poor boy. In a dog his age, this could be caused by something serious like heart disease. Heart disease can be common in senior dogs. I'd have him seen by a vet for this cough, and recommend getting a physical exam, a geriatric blood panel, urinalysis, and possibly chest x-ray done. If he does have heart disease, it cannot be cured but the symptoms can be managed with medication. Give his vet a call to make him an appointment. I hope this helps!
