Help the hound!

If you know me at all, you know I am a total sucker for an animal in need! When I saw this poor baby in the road yesterday, I had to stop and see if I could catch her. Hounds tend to be pretty elusive and I can't always catch them. However, she is SUPER sweet and came right up to me. I put her in my vehicle and drove her to Banfield so I could scan her for a microchip. No luck on the microchip and she isn't wearing a collar. She is also in TERRIBLE shape- her skin smells strongly of yeast and is very oily; she is missing more than half of her hair; she is covered in scabs and healing wounds. She did have fleas but I have taken care of that! She needs to be spayed and have some teeth extracted, but right now my main concern is her skin! That being said, our household cannot financially support another animal right now. We are maxed out at 2 dogs and 3 cats. Here's the big problem- no shelters or rescues around me are accepting animals due to being at full capacity. I can't do NOTHING for this poor, sweet girl. That's where you come in! I am asking, BEGGING, for help so that I may get this hound the vet care she desperately needs. Even with my discount for working in a vet clinic and doing the bare minimum, I am looking at a couple hundred bucks, easily. Please please please help me help this sweet pup! Every dollar helps.
