Had a nose bleed and sneezing up clots this evening
I'm sorry to hear about your dog's nosebleed and the clots she's been sneezing up. Given her age and her existing medical conditions, such as heart failure and a collapsed trachea, this situation is indeed concerning. Nosebleeds and sneezing up clots can result from various factors, including trauma, infections, tumors, or systemic issues like clotting disorders.
Considering the severity of her symptoms, especially with the presence of blood clots, it's crucial to seek veterinary care immediately. This could indicate a serious underlying condition that requires prompt attention. In the meantime, try to keep her calm and minimize any physical activity to prevent further bleeding. You can gently apply a cold compress wrapped in a towel to the bridge of her nose to help constrict the blood vessels and reduce bleeding.
Please take her to the nearest veterinary hospital as soon as possible for a thorough examination and appropriate treatment. If you have any further questions, please feel free to ask. Thank you.
