Goat's toes are pointed inward / crossing -- he can't walk without pain.

Ouch! It looks like they are severely overgrown, with the inside toe being more overgrown than the outside one. They're going to be hard to trim because they are so thick and hard so it might help to do it after you've had some rain. Or if you are like us and haven't seen a drop in ages, you can stand his front feet in a shallow pan of water for a few minutes before you trim. Make sure your trimmers are good and sharp. It looks like you should be able to trim those pretty aggressively without hitting blood. You probably won't be able to take them down as short as they should be for the first couple of trims, but you can make him a lot more comfortable right away and then shorten them more in the future.

Let us know how he progresses!
