Treats are an excellent way to help train your corgi.  However, you must be careful as to what kind of treats you are giving them and how often.  Corgis can become overweight and suffer health issues if not care for properly.  We use milk bones and pork chomps primarily. We normally only treat when training but the pork chomps we give to the corgis to chew on and a fully digestible. Try not to overfeed or over treat.
