Why is my dog struggling to breathe when sleeping? Is it serious?

In a dog Bailey's age, yes there is a chance it could be heart failure . You will need to take her into the vet now. The vet can do a physical exam and x-rays to see how her heart is working, and if she is in heart failure, the vet can prescribe medication to manage her symptoms. Best of luck.

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!

Thank you for contacting Petco Pet Education Center, formerly Petcoach with your question about Bambi. I'm wondering if she has something like a collapsed trachea causing her breathing issues. You see problems with breathing in the condition with excitement and exercise, and it does worsen over time. This can explain what is going on with her. Without seeing her in person, I can't say for certain this is the cause. I recommend having her seen by a vet in the morning. The vet can diagnose what is causing her problems, and can discuss treatment options with you. If she does have a collapsing trachea, treatment options include medical management or surgery. I hope this helps!

Thank you for using Petco Pet Education Center, formerly Petcoach! The signs you are describing can be caused by bloat, or dilation of the stomach, which can be a veterinary emergency and require surgery. This can also be caused by lung disease, a mass, or a foreign body in the throat - heart failure typically presents as rapid breathing and coughing, and usually develops over time. I recommend having Jersey seen by a vet as soon as possible, as it sounds like she may be developing trouble breathing. I hope all is well and am happy to answer any other questions you may have!

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

Thanks for using Petco Pet Education Center, formerly Petcoach! Abnormal breathing sounds can be a sign of many conditions such as pneumonia, bronchitis, heart disease, among many other possibilities. Given his breed, this can also be brachycehalic syndrome though that typically presents in a different way. I recommend that you have him 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!

Thank you for using Petco Pet Education Center, formerly Petcoach. It sounds as though your dog is in respiratory distress and should be seen by a veterinarian as soon as possible. Breathing problems are a medical emergency and should not be ignored. There maybe a life threatening problem.
