Horse with sensitive skin ‘twitches’

Dear Dr. Lowder:
We have a two year old halter filly. Bloodlines of Sockets. She developed a muscle twitch. It is sporatic all over her body. When she first developed it, we thought it was tying up. The first bout was at a show. It was very hot and she acted as though she was colicing. She would paw and would bite at her sides. There was noticable muscle twitching.

She had another bout when the farrier was here. The muscle across her top line tighted up to rock hard. We had to massage it out and walk it out. She will develop a twitch anywhere on her body at any time. They will move around. We did take her to a vet to be observed. They tried provoking it, but didn’t have any luck. She did have one when she got excited when we brought a stable mate in when we picked her up.

It doesn’t seem to happen at any one time. It can be standing in her stall while eating, while riding, anytime. We did do an HYPP test which came back negative. Also tried feeding her like a positive horse. We did the HYPP test because she is a heavy muscled horse. The blood work didn’t show anything out of the ordinary.

At this point (for about a year) she hasn’t had a major attack with the muscles becoming hard. Just the twitching.

Any suggestions?
Anne

Anne,

Your horse most likely just has sensitive skin like some people. As long as the major attacks have not reoccurred than I would not worry too much.

Thanks,
Dr. Lowder
