I was returning to my shop/house after going hunting when I saw all my dogs that I had sitting down were gone. I asked on chat where my dogs were and then relogged when I saw that it wasnt a bug. Then talkingmuffin1 asked Kendall_ if he had killed my dogs to which he replied
"noo" then talk said that he saw kendall_ hitting my dogs earlier.

i was standing in the shop and i saw kendall hitting one of toas dogs with his bare hand. the dog was turning red, dying. then he hit the dog and the dog went like into the wall and must of died

Kendall_ will be reverted, sorry for that. However your dogs cannot be returned.

In future - if you see something bad going on - hit F2 to take a screen shot. We'll guide you on how to upload screen grabs if required.

Screen shots help us to punish or ban the griefers quicker. Thanks for both of your reports though - it all helps

killing dogs are griefing?
I didnt know that...
I better not kill any dogs

Well its the same as killing anyones animals which they own. Any livestock (cows, sheep, pigs, chickens) which are in a locketted area is griefing, and killing any dog which isn't owned by you is too.
You destroying (killing) something which isn't yours

I know It's kinda of topic, but don't dogs attack if they're being attacked?

I think it's only when their owner gets attacked.

they will only attack if:

• The owner attacks you

• You attack the owner

• You attack the dog
