Bentley needs surgery

So this is our Bentley. Poor guy needs all his teeth pulled on his upper left side of his mouth. Unfortunately, me and my mother don't have the money for the surgery. We took him to the vet today and couldn't get the procedure done. However, I was able to pay for his antibiotic which lasts up to seven days and also need to pay for blood panel and cardiology before he can get surgery. He has an abscess, face is swollen, and is in severe pain. Bentley means the world to my mother and I. He's been there for many hard times for us and our family and we just want him to be okay. For anyone who would be so kind to help would mean the absolute world to us! Thank you so much!
