Puggles do tend to have a high degree of independence and this is why some people find it challenging to train them.
The easiest way to train your Puggle is to let the get used to a leash.
If you have a puppy the best thing to do is to put the leash on and let your pup drag it around the house.
This will help your pup get used to the leash.
After a few days pick up the leash and put a little pressure on the collar.
Once your puppy is used to it you can start to teach your Puggle to walk with you.
Holding a treat close to your dog's nose get his attention.
Once you have his attention you can start walking.
Give your Puggle the command "Let's go" and start moving.
Start by just walking a few steps and then stopping.
Once you stop give him some praise and the treat.
Once you start walking again make sure you practice changing directions, and the speed you walk.
After a few weeks of practice you'll be able to start fading out the treats.
Once you get rid of the treats you'll have to change directions to keep your dog's attention.
Within a few weeks you should have your Puggle walking with and having no problems with pulling.
If you still have problems consider using a gentle leader head collar.
They are extremely effective and will help you get great control and your dog will walk with you.
