Help needed

[mikes]

I have a 2yr old Beagle from good bloodlines I took her out yesterday hunting the weather was cold and there was about 5 inches of old snow very crusty. She jumped a rabbit ran it in a circle but then seemed to keep running the same track I never saw the rabbit after the first time.She has never done this before that I know of. I am new to beagling and I would like to know why and how I can fix it.
