Idk what to do....

My dog is sick and I simply can’t afford to take her to the vet. I already owe $300+ at the vet and more money at my doctors offices...

She has a runny nose, she’s sneezing, and today her runny nose liquid has turned a light brown color.

She is playing fine and drinks lots of water. She’s been eating, she’s never been a big eater though, she just munches.

Idk what to do. I’m gonna get her some soup and put the humidifier on for her and keep her warm and makes sure she sleeps. I just wish I could take her to the vet though. I can’t till tax returns come though...
