Trying to get my horse through a nether portal
Is there any ways I can get my horse into the nether without it suffocating in the portal and dying?
Solution 1:
A default 4x8 nether frame should already be large enough to fit your horse without you suffocating, but if you're still experiencing an issue with suffocation you can make a larger nether frame. With Minecraft's 1.7.2 update the size limit of Nether Portal frames was made as large as 23x23 blocks of obsidian - more than large enough for your horse, or any creature really.
