Top 10 Successful Dog Training Tips

Recommended Answer:
What has worked best for me is by putting my knee up into their chest as they jump up. Not enough to hurt them, but enough to where they cannot make contact paws to chest...at the same time, tell your dog 'no' in a firm voice. You must train your dog to not jump, rather than expect other people to know how to keep them from jumping. What ever you do, don't put your hands on your dog to push him off. He may think you are rewarding him and continue to jump in order to get your hand contact. I use a horse spray called Bronco on my dogs...It works great. Try it on your horses.

How to Begin a Dog Training Career

• As suggested, raising your knee is the easiest method. However, I have been successful by stepping lightly on their back toes. Use either method along with a consistent command.
  
  After you successfully get the dog off of you be careful about treating the dog in any way that could be interpreted as praise. Withhold that "good boy" for when he does an action correctly, not when he has been corrected for doing an inappropriate action.
  
  For terms, I prefer "Off." Whatever term you use just be careful to keep one term for each desired action. For instance, "Down" seems okay until you want him to lay down. The choice of commands is yours to make just be consistent.
  
  To keep flies off horses I have to defer to someone who knows horses better than I.
