Do you have any videos about training terriers? My terrier puppy has an aversion to his harness and leash

All of our dog training is suited for all breeds unless you are looking for terrier-type sports like earth dog. I have owned a terrier for the last 11 years and will be getting another in the next couple of years. They can be slightly harder to motivate for some activities compared to a typical a herding or sporting breed. I trained my terrier and Shih Tzu with the same methods I used for my Malinois and German Shepherds

Is there a specific training activity that you are looking for?

This sounds familar :) I had a Corgi that was like this years ago.

My little Border Terrier was also extremely sensitive as a puppy. Independent but sensitive so I had to really read her body language. I put the equipment on my puppies and don't actually use it. I let them (with supervision) just walk around with me, dragging the leash (make sure it's VERY lightweight) For puppies that show avoidance I get out the equipment and hold it, don't even attempt to put it on. I use extremely high value food so when they see the equipment they anticipate something extra special. You need a hungry puppy for this. I personally wouldn't go to the head halter at this point because even compliant and easy dogs often find this very aversive at first. Just hold on to it and don't use it at this point.

You can always go to pressure (YOU MUST) later but for things like training equipment I want the puppy/dog to be happy about it because it means good things to follow.

I'd study the puppy course you have and if you can, do lots of food chase games and restrained recalls. I wouldn't worry about real "obedience" right now, you want to build engagement and a positive association with you and training equipment.

Terriers are bred to be independent and like to self entertain a lot so you have to look at it from the puppy's point of view and make yourself the best game around. It will be worth it in the long run.

You may want to get a tiny snap and very thin paracord and fashion a line to attach to his collar or harness. Traditional leashes are often heavy for little puppies and can suppress them. you may be able to find this at a hardware or farm supply store.

We do offer a lightweight slip lead for small dogs/puppies as well. It might be a good intermediate step between a collar and leash to try it?

Dogs/puppies are very resilient and I've been in your shoes! Put the energy into creating a relationship and the training will be so much easier later on.

The training material also helps create a dog that loves to learn which makes training easier and fun for everyone involved. :) We just don't start with the actual obedience behaviors right away but all the building blocks to "learning to learn" and engagement. Don't let other dog owners or trainers who don't prescribe to this way of working with dogs discourage you.

I've taken dogs as old as 9 years that had everything done "traditionally" with them their whole life and changed their mind about training just by going back to the basics of creating a relationship and engagement first, so you'll do fine. Have fun with your puppy! :)
