A training question for dog owners

[Zeuceone]

A trainging collar is used when walking the dog and has to be positioned properly(ie. a prong collar). Have you tried having him around other dogs to get him use to them? Try taking him near a house with a dog and have him seat close by. Give him a treat if he stays in a seating position. As he gets more comfortable move him closer but keep a bit a distance from the fence.
