I have a 25 year old oldie - she has arthritis, has been fully retired few years now and has been on a daily (sometimes twice daily if she’s been twatting about) dose of Danillon for about 2.5 years
Back in November time she developed diarrhoea. Had a vet out, checked her over, blood tests, etc, etc - all fine, couldn’t really find a reason for it, no signs of damage from the Danillon, no cushings, no laminitis, no colic, no outward signs of ulcers (although she wasn’t scoped)
She was fine in herself, eating normally, drinking fine, didn’t lose any weight, no change in her behaviour
Cut hard feed back to just chaff, then tried her on pink mash, a gut balancer, had a good worm count but vet advised to worm her anyway, and the vet suggested a gut sponge. She has a joint supplement and an OAP vit/min supplement that she’s been on for years. We tried wet hay, dry hay, hayledge. All sorts.
It continued all through winter, sometimes poo was a little more formed, sometimes like cowpats. Vet still couldn’t find any particular reason for it or any underlying conditions and the fact that she continued bouncing around like a horse half her age, we just managed it as best we could.
3 weeks ago, it stopped. Almost as suddenly as it started.
Nothing in her management has changed, grass has started to come through but in the past that has usually been the cause of softer poo rather than the cure
Same thing happened last winter, November time she developed diarrhoea but it cleared up after a couple of weeks. This time it’s lasted months.
Vet seems to think it’s just an age or ‘her’ thing however I am keen to look at her management and see if we can make changes before next winter
