Good luck tomorrow. You probably wont sleep all that well tonight I'm sure.
Sorry, cant help with the name of a dog tracker.
If you dont find a dog, dont be discouraged. A pink mist is a good sign and a double lung hit can very well be lethal quickly with very little blood. If you dont get a dog, go very slow and when in doubt, keep to the same general line and the path of least resistance. A double lunged deer pretty much goes on a straight death run and should pile up in less than 150 yards. If you only got one lung, you did the right thing to back out. It can be lethal but can take much longer.
Good luck!!!
