A minecraft mod that respawns dead tamed dogs?

So a long time ago I was watching Youtube and this guy (don't know his name or the name of his video, sorry) had this skeleton dog named Grim on minecraft and I remember that at one point Grim was killed and the dog just respawned beside him again, name and all like nothing happened. Though I think the dog repawned sitting down, which in my opinion would be a pain in the but, say your dog respawned sitting in a place where you can't find him and he can't teleport back to you if he's sitting you know? Anyways, I have this tamed wolf named Scoot who's a great little pal of mine, but I can't take him around with me on dangerous minecraft missions because I'm afraid I'd lose him for good. Now if anyone knows of a possible mod that respawns tame wolves to you, preferably standing up, that would be great!
