I load Minecraft snapshot 13w24a, and enter my multiplayer map (I run the server). I have a doghouse (5 wide, 5 long, 2+ blocks tall) next to my "house". Upon the world loading I can hear the dogs whining, and when I check on them all 6 have their health depleted to the point where it takes 3 zombie meat to heal them back to full health. Also, I leave them sitting in the dog house, but when I load the map they are all standing and in my "house". I have been the only player on the server today.
What I expected to happen was...:
My dogs are the same as I last left them - sitting in the dog house, with full health.
What actually happened was...:
They are teleported to my house with their health greatly depleted, whining.
Steps to Reproduce:
1. Start Minecraft snapshot 13w24b
2. Load map
3. Listen to dogs whining

An update - as usual, I fed my dogs upon loading my world so they would quit their incessant whining. I went cave exploring out a bit far away, then came back to my house. My dogs' health was like it was when I loaded the world - depleted. I am thinking this is an issue that happens every time the dogs have to be re-loaded rather than the entire world.
A second update - dogs are no longer teleporting into my house upon loading, but still are losing their health when they themselves are re-loaded. I just did some tunnel mining and when I got close to my house (unsure how many meters, I'll check next time) the dogs were teleported to me, with their health depleted.
Happens in singleplayer 13w25b.
just logged in to snapshot 13w25c updated today 20th . issue is still not resolved. my dogs were completed in health and needed 3 zombie flesh as before to regain health.
Actually confirmed this is still an issue in 13w25c.
Strange, I'm able to reproduce this now but wasn't able to after my fix. Investigating.

Reopened for 13w26a
Although this is labeled as fixed in version 1.6, it still happens to my dogs in version 1.6.1 whenever i load my world (just the low health part).
The same is happening to me. I had this problem when I downloaded the 1.6
snapshot. I even lost tamewolves in older survival worlds. After reporting
it it was resolved in a few days. On the 2nd I downloaded 1.6, and like you
the glitch is back,

I am actually having the teleportation issue still, but I'll report that elsewhere.
I have no idea to where I should report problems! There are lots of forums
etc ?... My biggest problem is that after finally finding a herd of horses
and tamed one, I CAN'T GET OFF !!!!!!!! Shut everything down, rebooted, but
still riding into the sunset, and the sunrise, and the sunset.......
