My very nice 19 year old CSH mare is PPID, and controlled with Prascend. Religious muzzling and medication keeps her comfortable normally, and she was in full work until this fall. I had never had more than mild foot sensitivity with her, a feeling of slapping her front feet down under saddle, and that disappeared with controlling her PPID about two years ago.
Come mid-October, we had a very wild swing in temperatures, from overly mild to very cold in about 24 hours. This lead to a nasty colic and laminitis flare up (we’re not sure which precipitated the other, to be perfectly honest). Careful management had her back doing light walking hacks under saddle by January.
Fall and winter had continued to be quite mild here in Southern Ontario, until we got blasted just before Christmas with a more wild temperature swings. We went from +10C to -30C and back to +14C over about a 10 days, and I have been dealing with a sore horse.
She’s not nearly as bad as when she flared up in October. She’s bright, alert, eating well, and wants to go out with the horse horses. She is short strided though, sits back on her hocks when turning, and exhibits many other classic signs of laminitis. Feet are cold though, no bounding pulse is present. I have been keeping her in with deep bedding, and did give her banamine on her worst days when she initially got sore.
Not one thing has changed with her management to cause this recent flare up, and Googling has taken me down the path of winter laminitis, which sounds similar to Reynaud’s in people? Microvascular changes in the hooves due to prior laminitis making the foot extremely susceptible to cold, and therefore quite painful. Anyways, they suggest managing the horse by keeping the feet and legs warm - how on earth would you accomplish this in Canadian winters?? Even boots and bandages aren’t going to help much past about the first 10 or 15 minutes of turnout. Short of putting hot pockets in hoof boots and bandages…
Has anyone else dealt with this? Is it a recognized thing now? It’s the first I’ve heard of it, but I am also lucky enough to have never had to learn the ins and outs of laminitis management until now. I have Googled my little heart out, and it’s a weird combination of some reputable sources, a lot of herbal supplement companies pushing their products to “treat” winter laminitis, and some absolute whack-a-doo websites with questionable write ups.
