Reddit reviews Ultrahund 'Boss' Adjustable Lead, 5/8"/4-6', Yellow

I saw the picture you posted - what a beautiful girl. I've also got a Penny. As for being overwhelmed, know that is totally normal, so don't stress. Getting her signed up for a class asap is also a great move. If you can have a private trainer come over even just for one or two sessions at home, he/she will point out a ton of things you could be doing better and get you started on how to correct them.

As for leash pulling, here's what we did:

• Get a six-foot lead that is easy to grip. Here's the exact one we got: https://www.amazon.ca/gp/product/B016KCD0F8/. It's bright and she didn't want to chew it as much as she wanted to chew the nylon one we started with. You want to get to the point where you can walk with your leash hand totally relaxed at your side. At the start, you'll find that you naturally raise that hand to shorten the lead distance, but try and work to keep it down so the pup has 6 feet of freedom.
  
• Start your walk. From when you leave your house (including on your driveway!), the second she starts to pull, stop moving right-away and wait for her to stop pulling so the leash goes slack by her moving back towards you a bit. This can take some time, be patient. You want her to start realizing that loose leash = green light, tight leash = red light, and that by walking nicely, she'll get to wherever she's trying to go.
  
• When she is walking with the leash slack (often only for a few seconds at the start), praise her constantly. We use "good walk!" to let her know that is the behaviour we want, and then as soon as she starts pulling, we use a correction word like "uh-uh!" and stop dead in our tracks so she knows that's not OK.
  
• We started this late, and so we've dealt with having to correct this by breaking the habit, and while it has worked, it was very slow and makes your walks very slow as well, as you're constantly stopping. I really wish we started this the day we got her.
  
• Lastly, keep your walks short while she's learning this so she can keep her focus, and make sure everyone that walks her understands that the second she pulls, they stop walking.
  
  We also introduced a second exercise to help reinforce this:
  
  

1. Go somewhere that is free of distractions and smells, we used a paved pathway behind our house.
   
2. Have a family member/friend go stand a little ways down the pathway, while you hold the lead.
   
3. Have your pup walk slowly towards that person. Naturally, she is going to be pulling like crazy to get to them. The second she pulls, stop in your tracks, turn her around and walk back to where you started.
   
4. Keep repeating this until she can walk from the start to the person without pulling. This can take a long, long time but it worked wonders for us.
   
   Sorry this got so long. Good luck! We got some of these tips from http://toldin.com/content/teaching-vizsla-walk-loose-lead
