All jokes aside, the vet came out for spring shots and we discussed a lot of topics. She pulled blood, we decided to up his grain to 4 quarts twice a day, as well as adding in alfalfa cubes/hay stretcher. I also started treating for ulcers, sort of as "just in case" option. He hasn't lost anymore weight but I wouldn't say he's gaining much.
The blood work came back just fine so hopefully the addition of more hay in the form of cubes or hay stretcher plus treating for ulcers will help!
I also threw him in the round pen yesterday for a few minutes. I haven't been riding even though he's sound because he is quite skinny and I don't want him to burn any more calories than he needs to. Plus, honestly, is his saddle even going to fit?!
Also, I've been eating toooo many donuts and cookies so I've got a few pounds that I could lose from riding. :)
