Hi Joel,
I'm in Mesa too...
It's to early to tell if you'll need an e collar. Chance's are you will, but as far as that goes it's another tool that can be employed properly or stupidly.
Start training now! Any book by Wooters is a good place to start whilst getting to know your pups. Start budgeting for a little professional help though. I highly recommend Jay Amos in Ashfork. I won't print here what I think of most dog trainers but I will say that Jay is good. And that's coming from someone who was raised in the dog training world.
Don't hunt the pups with the old untrained dog...
If you got your pups from Ken Levy, don't be suprised in they get as tall as you.
This is my RugerSaurus -only one year old next to my 4' tall daughter - he's grown since this pic. Does anyone know a custom saddle maker?
