Scout has never had any injuries. It’s also interesting because this same incident happened during the summer, but he got better again within just a few weeks. And then he came up sore in the fall, but was better in less than a week. My farrier also has told me the same thing with the frozen ground. Scout’s due for a trim now anyways so I’m going to see if the farrier can rule anything out. If not, looks like I will be calling the vet. Thank you both for your input!!
