I use treat/reward training, never ever harsh physical touch…….. but of course cuddle and smooches are part of the training.
Training includes the basics of sit, stay, leave etc., but also recall, jumping and barking in the later courses.
I can look at individual issues with a puppy.
Training a dog is like bringing up a well behaved child. It takes time and doesn’t happen overnight. The best thing you can do whilst training your dog is to reinforce the rules, be consistent and give your fur kid a safe and loving home.
