|Here is a picture of Joey, for those interested.
My brother and his girlfriend recently adopted a pug. He is about ten months old and mostly well behaved. They want to take him swimming but every time he gets near the water, he begins walking backwards and whining to avoid it. I discussed with them to provide the puppy with treats as they get closer to the water and maybe stand in the water themselves as they give him treats. This method can work with his favorite toy as well. Gradually introducing him closer to the water while providing him with stimulus that he enjoys or relaxes him will hopefully get Joey comfortable enough to swim.
As discussed in the text, Mary Cover Jones used systematic desensitization to treat a two year old boy named Peter who had an extreme fear of rabbits. Jones's treatments involved giving Peter cookies while presenting a rabbit in front of him. Over the next few months, numerous sessions resulted in the rabbit gradually getting closer to Peter as he ate cookies. Eventually, Peter would eat cookies with the rabbit on his lap. The gradual conditioning procedure eliminated Peter's fear of rabbits through systematic desensitization.
