First off, we recommend waiting until you can touch your dog before trying to train them to walk on lead. Follow our guidance on how to desensitise your dog to having a trailing line and collar placed on and off.
Pretty much all the Romanian dogs will have been moved around or transported with a noose-type catchpole prior to their arrival on the UK and lots of tension around the neck and trigger these memories.
Catchpoles are not something we like, however, shelter workers are reluctant to touch dogs with their hands. International Dog Rescue are working on building their own shelter where they will handle the dogs much better.
If you just put a lead on your dog and drag it around the garden you will find that it resists and will fight against you or try to pull away which will damage your relationship with the dog. If the dog is frightened or pulling away STOP.
