John, as a U.S. Navy vet (served shortly after the first gulf war/ non combat times) I want to thank you for your sacrifice brother. I greatly appreciate what you gave for this great country we live in.
I'm also a DS newbie w/ a 6 1/2 mo/old female that's a handful! I've been through the puppy course & am about to graduate this coming tuesday from the basic obedience course. One of the main trainers there is a DS pro w/ many champions under his belt so I've been lucky. He also holds a Schutzhund club that I've just started attending. I'm a total novice, but if I can help in any way I will do my best.
In response to:
#1 Likely a size small tightened all the way up. It's what my Indy needed at that age. I went w/ the
'rabbitgoo' brand & have been happy w/ it. I will say, you may 'want' to only use a harness, but you will quickly find either through trial & error or from a trainer that what you 'want' to do & what a DS dog needs are two very different things. In the end you will end up needing a harness, a flat collar, a prong collar & maybe an E-collar to effectively train your dog. You seem to need ALL the tricks to work these dogs best!
#2 The training facility I attend,
Landheim K9 raves about 'Taste of the Wild' so I'd say you are good there.
#3 You're going to need to be doing more than just walking her. DS need activity to be fullfilled otherwise she may begin acting out. These dogs can run for days & NEVER get tired. Simple fetch will do for now until you begin her basic training. Get 2 identical
non-toxic balls (NOT tennis balls) & start playing a bit. You'll quickly find just how 'ball driven' she is. Toss one & as she's bringing it back entice her w/ the other by moving it around a bit. Keep it going how ever long you feel like.
#4 I keep my Indy in a dog run during my working hours, but she got a lot of crate time after work when I first had her. They are a handful & don't feel bad keeping her in the crate allot at first. I was told that it's perfectly normal for this breed. What I did & still do at times is put her in the crate when she's a bit too wound up. Just make sure to let her out to go to the bathroom & get some water at least every hour. I'm able to keep her at my side much more now & she will lay on her dog bed & relax as well. She sleeps in the crate every night (8 hours) though w/ no problems.
I hope I've helped you a bit!
P.S. Get yourself LOTS of tough chew toys. You're going to need them! My Indys nick name is 'The destroyer of toys'...
(Disclaimer: I am a novice. I fully understand this. The answers I have given are all based on specific DS info my trainer has relayed to me & my personal experiences w/ this breed thus far.)
