I have permission from the horse's owner to go into a little more detail:
Owner offered at the outset to pay livery costs for horse (we'll call her A); LJ declined as it was doing her a favour as A would be company for one of her other horses with specific management needs similar to A's.
Owner brought enough feed, medication and supplement at every visit to cover the periods inbetween visits. LJ didn't have to pay for any of these things for A (but is now claiming that she bought it all).
Owner offered to bring a trailer-load of A's accustomed bedding for her stable; LJ declined as she wanted to use a bedding of her choice.
Owner left over £2k's worth of equipment for LJ to use on any of her horses, not exclusively A. LJ still has the majority of that equipment - after A's death owner gave her permission to sell it if she wishes.
After A's death, owner reclaimed her bridle and saddle - both were green with mould as LJ had taken no care of them while they were with her.
Owner asked, and LJ assured, that A be turned out individually as she didn't cope well with being in a field with other horses. Unbeknown to owner LJ disregarded this request, turned A out with other horses and she was consequently bullied. Owner has photographic evidence of bite marks to A's back and neck.
There are also allegations that LJ insisted on unnecessary and invasive veterinary procedures to be carried out on A despite no evidence or history of a medical problems. (Owner has some evidence of this from LJ's vet who is cooperating with the PCC investigation.)
Owner never gave permission for A to be written about in LJ's articles.
LJ didn't do A's owner the courtesy of informing her privately that A had died; owner found out by reading her newspaper column.
I know A's owner and she is a 100% straight, honest, decent person. She genuinely thought that LJ, as patron of an equine charity for whom A's owner has done a lot of fund-raising, could give A a "perfect" home. That perfect home turned into a nightmare resulting in the unexpected death of a previously-fit and healthy A within four months of her joining LJ.
