Springfield OH

Description

I have a jack Russell, rat terrier, Chihuahua mix she will be 4 Jan 16th, She ate something by my neighbor's fence I believe they threw over she's now attacking me randomly never breaking skin but hurts n other pets, other than that big big issue she's great with strangers etc. I'm fresh out of a dv relationship I can't afford behavior training. My friends say my only option is putting her to sleep, I can never do that I couldn't forgive myself, any advice or rescues. I know she needs a huge yard to run she goes out to potty n back in I'm disabled n she gets out just cheap fencing, it's probably built up energy idk But please please help me any advice or rescues. Her name is Daisy I'm not rehoming her not unless you have a big farm for her to run n burn energy n money for vet when needed.
