My new dog attacked a chicken yesterday. There appears to be almost no visible injuries. She can just about stand with support but cannot lift her head. As such I cannot feed her or give water. She is just lying in the straw. Her breathing is regular and obvious but not especially laboured. This happened 18 hours ago. There has been no improvement during this time. Possibly slight deterioration. I don’t want to end her suffering if she might improve but I feel so awful to let her stay in this state. Can anyone advise?
