Buttons needs an MRI

Hi, my name is Ana and I am asking for help for our family dog.

Buttons is a mix of Shitzu and Boston terrier. I met her as my very first foster doggy 11 years ago. She picked me but I couldn’t keep her at that time. My agreement with the foster group was to fostered and adopted out 3 dogs before being able to keep one. When she was adopted I asked her family to please call me if they changed their mind. She was with them for less than a year. I did eventually receive that call that made her mine, she has been an amazing part of our family. Buttons is a support animal, I have suffered from hypertension since the age of 35. When my blood pressure is high she helps me keep calm. Throughout this past year I noticed her energy declining, and last month she started to bleed through one of her nostrils. She was rushed to the emergency room and unfortunately, I was hit with a bill of over $1000. I opened a care credit card to get through that night. An MRI is still needed and I cannot afford it. My kids and I want to know what is inside her nose and get her the help that she needs. We don’t want to say goodbye to our dog if there is still hope of saving her. Please help.
