TIP # 1: ASK FRIENDS OR FAMILY TO HELP WITH TRAINING
Many dogs only practice certain undesirable behaviors, such as jumping to greet, around visitors or strangers, which makes it nearly impossible to extinguish those behaviors on your own. Ask friends or family to help with training. Many, especially dog lovers, will gladly oblige!
TIP #2: REWARD OR REINFORCEMENT?
A reinforcer is a reward but reward implies something that is considered to be good by the giver and hopefully by the recipient as well. A reinforcer, on the other hand, is very specific. A reinforcer is good because the recipient considers it good and because it serves as "pay", in that it makes the recipient do something to receive it.
