To clarify, it is not that I don’t like the advise of the posters, it is several did not answering the question or I didn’t understand the response. Sorry it came out as snarky! Hopefully the additional info/answers below clarify any confusion.
To reiterate, the question is: Is it safe to ride at 4:45 if he is given the gel at 1:30. The vet said it would be fine, however, I don’t have much experience using sedatives and wanted to double check. I absolutely do not intend on riding if he is sedated at the time of the lesson. This includes if I do it and he is still sedated. If it matters, I ride Dressage at Training Level so no jumping or much lateral work.
I have also emailed the question to my instructor to get her option. She is very responsive to emails and I expect a response either tonight or tomorrow morning.
I just want to make sure that what I do is safe for both me and the horse. I am trying to balance the need of the horse (getting too hot and then potentially too cold if clipped) versus scheduling issues with the lesson and weather.
In the past when I have run into this situation, I just clip the underside of the neck and do the rest of it later. In this case, I don’t want to break the clipping into two times as I try to avoid medicating the horse if unnecessary.
Moving the lesson is problematic as we are already having to reschedule next week’s lesson. Our schedules are such that there are not many time slots that I can make-up a lesson. Typically this is not an issue.
As to clipping after the lesson,I would be worried. I like to rinse the horse off afterwards to get rid of the loose hair to prevent itching. If I do that, since his legs and belly will still be yak like, I wouldn’t be able to put on a blanket as it would be several hours later before he was dry. Plus I like someone around for an extended period after he sedated in case there are issues. If I stayed, this would put me at the barn really late.
Lastly, THANK YOU to those who have answered the question.
