Q: Two weeks ago I bought my first horse, a 12-year-old 16hh, 7/8
TB. I have noticed that when he passes water it is a normal colour
but at the end of the flow it tends to turn dark brown. Is this
symptomatic of something serious?
Equine urine is normally either colourless or yellow and quite cloudy.
Colour and cloudiness change as the bladder is fully emptied. I
think it would be best for you to take a sample of your horse's
urine to the vet and ensure it is tested very soon after it is taken.
It should be refrigerated if not analysed within half an hour and
the sample should be taken in the middle of passing water.
to stand normal urine often turns red/brow but the vet will look
for sign of too much protein, blood and white blood cells
in doubt ring for advice. We're here to help.
