I am sorry to hear you are worried about Brandy. My name is Rebecca. I am a veterinarian and will do my best to help.
How long has she had a hard time breathing? If you check her gums, do they look pink or pale to you?
Is she eating, and drinking?
Is Brandy spayed? This is very important for me to know.
I am worried, too, from what you are telling me and if her gums are pale, or if she is not eating, this may be something that needs more than home remedies. Let me know how her gums look, and if she is spayed.

I hope to hear back from you soon. If she is not spayed, I am particularly worried.
