I noticed her gasping Friday afternoon, standing in the same place, not grazing. When I checked her at dusk she was in a sleeping box still gasping. She hadn't eaten, crop was empty. We brought her in the garage and put her in a rubbermaid tub. I googled and got the fenbedazole for horses and gave her a pea size (0.4g??) Fri night, sat twice, sun twice and this morning and she seems to be worse. Her comb is bluish and she's no longer standing. As of this morning, she only sits, mostly head down, eyes closed. She will swallow pellets if I can get them in when she takes a breath and she will swallow water and meds. As of last night I did see her drink water out of the bowl. Today I also gave her wazine by mouth and she just let really watery stool that smelled like burnt matches. I'm assuming from all meds and not much food. Any help would be appreciated.
