He's too Friendly!
"The trouble with my dog is hes too friendly" is not an excuse for allowing your dog to intrude in personal space. What your uneducated eye sees as friendly, I see as dominant excited, then calling them repeatedly while chasing them round and getting flustered makes YOU look stupid. What you should be admitting to is "sorry I've been lazy in educating my dog in teaching them what being social is (respectful of space and calm) and teaching them a good recall" your dog may be friendly but that doesn't mean what its doing is polite to another dog or human. So many uneducated defensive dog owners around. When you try to give them a little advice they jump down your throat even when they see how well behaved your dogs are.
