My 30 yr old shetland got out of her yard and I assume she ate a lot of green grass as well as some Barley that is growing in the paddock. Yesterday I found her lying down and she would not get up, she was very bloated and I could hear a lot of gut noises. I decided not to call a vet because of her age I would have her put down if she was in to much pain and did not recover. I gave her some psyllium husk which she ate, and about 2 hours later she was up so I walked her around for a bit then put her in her yard. My 4 year old niece asked me why she was walking funny and when I looked she appeared to be walking on her heels with her toes up (back legs only). She is still doing the same thing today. Is this a symptom of founder? I have looked it up but cannnot find anywhere that says it is. She has foundered before (before I owned her) and she is not standing in the "rocking horse" stance that is typical of horses with founder.
