My puppy acts crazy on leash. What harness is best for puppies?
Training a new puppy can be hard work and I am going through this myself. Start by just leaving the collar on the puppy at first until she gets used to that. Next, attach a leash to the puppy, in the house and let her drag it around the house. Keep an eye on her at all times so she doesn't get snagged at all. Reward her with lots of praise and treats but do not hold the leash yet. Once she drags it around and runs around with it, start picking it up. Follow her around the house, tossing treats so she will get them. Do not pull her and do not try to make her go your way. Next, take this to the backyard and let her drag a leash there. Then start letting her walk around the back yard while you trail behind her holding the leash. LOTS of treats and praise for any forward motion. be patient! Try some squeeze cheese on a big plastic or wooden spoon to get her to move froward if needed. You can also get her used to a harness. For a puppy, or any dog, I recommend an easy on harness that the dog steps into and snaps over the back. For a small puppy, you could also use one that looks like a small vest as well. Use lots of treats and cheese to put the harness on so the puppy is not afraid and thinks the harness is good.

Vet Q & A
My dog's harness broke. Can you recommend a comfy, cute new one?
How lucky of you to visit Germany recently! I would check to see if it's possible to ship the ones you like from Germany to Bosnia & Herzegovina. I'm not very familiar with the inventory of dog harnesses in your country, and given that many things can easily be shipped, it might be the best idea to have the cute and comfortable ones you say in Germany shipped to your home :-)

Training & Behavior
My energetic dog slipped his collar. Is a harness better for security?
From the perspective of him getting loose a harness could be more secure. I find, however, that this encourages them to pull more. I like the easy walk harnesses the best or even the gentle leaders. I would also recommend some obedience training as they can help you Willy off leash management

Head halter for dogs: Training, muzzle, & loose leash walking help?
Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Personally I love the gentle leader muzzle harnesses. It provides owners great control of their dogs. It does take a while to get the dog used to it and they still want to rub their faces on people to get them off. They do that in the exam room with me. I would gradually increase the time you have it on in the house before going on walks and give him treats or peanut butter while he has it on. That way he associates it with good things. I do think so people think it is a muzzle but more and more people know what they are. Personally if it makes your life easier I wouldn't care what some people think. I think people think more highly of the gentle leader than the prong collar. As for walking on a loose leash, it may help with that but it really depends on the dog. Some will take advantage when they know the leash is loose. The best thing to not have a dog pull is to train them to "heel," which is easier to do with the Gentle leader. I hope this helps!

Vet Q & A
Puppy pulling: Is a harness or collar better to prevent neck injury?
I generally recommend using harnesses rather than collars for walking. If a dog pulls excessively on a collar, they can cause irritation to the trachea (windpipe) or develop neck pain or injury. Some harnesses, such as an EasyWalk harness or Gentle Leader, are designed to minimize pulling and can be quite helpful for training. Teaching Jasper a "look" command where he learns to watch you closely while on a leash is quite helpful. All of that said, I still like dogs to wear collars so that their identification tags are readily accessible in the off chance that they would run off. I hope this helps and that all goes well!
