Because lettuce isn’t very rich, this means that horses can eat slightly more lettuce than other treats. That said, you shouldn’t feed your horse more than 2 pounds of lettuce at any one time and you shouldn’t feed them lettuce more than once or twice a week.

Just like all new treats, you must introduce lettuce into your horse's diet slowly. This is to make sure that your horse isn’t allergic to lettuce. And it also gives your horses sensitive digestive system time to adapt to the new food.

You can do this by feeding your horse just one or two leaves of lettuce at first. Then you should monitor your horse for signs of digestive discomfort for the next 24 hours. If your horse seems fine then you can gradually increase the amount of lettuce in its diet. However, if your horse has excessive gas or diarrhea after eating lettuce then you shouldn’t give it any more.

Another thing to consider is that most types of lettuce contain potassium. This means that you should speak with your vet first before you feed it to horses with HYPP. Horses with this condition can’t have too much potassium in their diet because it can make their condition worse.

And lastly, it’s important to know that not all leafy greens are safe for horses to eat. You should never feed your horse Swiss chard, kale, spinach or endives. These contain lots of oxalates which are toxic for your horse. And never feed your horse cabbage leaves, these can cause bloating and colic in horses.

How to Prepare Lettuce for Horses

The leaves of lettuce don’t pose a choking hazard to your horse. However, the tough stem of the lettuce can be quite hard. So you should break the leaves off the stem and only feed the lettuce leaves.

And it’s really important to wash and dry the lettuce before feeding it to your horse. And while you’re washing it check for any moldy or wilted leaves and remove these. Wet, slimy or mouldy lettuce can be really bad for your horse. The bacteria found on moldy lettuce will cause bloating and possibly colic.
