So we have recently adopted an 8 month old Yorkshire Terrier, long story short we are first time dog owners, feeling a bit overwhelmed so we have decided to go to some puppy classes with him.
We have found a local class led by a lady who claims to have 14+ years experience of dog training, she has stated that we should bring the dog wearing a "training collar" and lead NOT a harness.
Now everything I have read on the internet says you shouldn't ever walk a Yorkie on a standard collar and lead due to their increased risk of a collapsed trachea. Surely an experienced dog trainer would know this? Or maybe it's ok for short periods of training?
