ok i ride in the west reg. with an 11 year old arab 
and starting last year she started to get thumps on
some rides, i use commercial e-lytes and give her a
partial dose every time she drinks but still she is
thumping at rides but her hydration, skin tenting
and basically every checks good except for the
thumps. now at the last ride she did the vet said
in her opion it's not a problem since everythig else was good
but she has been pulled at anouther ride when everything else was good. Any ideas?
