    Training Tips :
    If you catch your puppy in the act of eliminating inside, clap sharply twice, just enough to startle but not scare him. When startled, the puppy should stop in mid-stream. Immediately run with him outside, encouraging him to come with you the whole way. Allow your pup to finish eliminating outside, and then reward him with happy praise and a small treat
