There are a lot of questions to be asked and why don't we hear what the trainer has to say to defend himself? Do you thing a highly recommended trainer would abuse and animal like this then send it home? His whole life and career would be ruined. How was the lamanitis caused? She was giving a lot of minerals, what kind of minerals?
Lets take a really wild side and say that when she got the mule home she did the damage!!!! How sick is that? Now she wants to blame him for it! There are amazing people in this world.
All this is going to be is a he said she said. She'll have to have her witnesses and he'll have to have his.
WHY didn't she take the mule to vet right after the trainers??? She said she's a nurse,,, any nurse would've seen the horse needed medical attention asap. Blood work, xrays, ect.
Don't jump on a mob train because someone said too and you said how high on the way up. Ask questions and find this trainer to defend himself. I would personally like to hear his side too.
