Hi! I have a 3y/o that I purchased in the fall. I suspect that she has been on a dry lot since she was a weanling due to the prior owners not having pasture. I'm trying to slowly reintroduce her to grass because we like to let our horses be turned out rather than up in dry lots 24/7. The last 2 weeks I have been letting her graze our yard 1-1.5 hours in the evenings. Is this too much exposure to risk laminitis? I have never dealt with this so not sure what the signs of too much exposure would be. Any tips for this transition would be super helpful. Thanks!! 

I start with 15 mins a day grazing for 3 - 4 days, then up to 30 mins a day for 3 - 4 days, then a couple of hours a day for a week; then up it to 6 hours a day for a week, then 12 hours for a week....then I turn them out full-time.

Like Delta Cowgirl said do it real slow. I have a IR gelding and Spring grass is a no no for him, the new spring grass is loaded with sugar, and when the sun is shining bright is when it will really load the grass with sugar, late in the evening when the sun is going down is a good time to let horses graze on the new grass.
