I cant believe some people get away with this...?

I was asked to go look at a pony a friend had paid 1500 quid for as a 14.2 14yr old,100% ideal first pony.My god she is in her late twenties early 30s very poor,Mud fever upto her arm pits totally Lame,Anyway your getting the picture.I suggested firstly the vet to come out,then to stop the cheque,it seems they paid a small charge un cashed it immedately. this poor old mare has had a major trauma on one side broken Pelvis a shaft into her neck un shoulder,it makes me sick to the stomach thinking about the pain she must of been,Anyway shes been with me 6wks now has tripled her size,had Heather Dunning out (the best lady in the world if your a horse is in pain) is always going to be stiff but is very happy now retired.If we can keep her upright in winter she will stay till her last breath,Pain free un very much loved.I just wish we could put the Bast...s to sleep that keep doing this sort of thing.
