I actually think group classes would be better and $161 is not unreasonable. After reading the posts about Jasper, I think it is almost as important for him to socialize as it is to learn basic commands. Some trainers will also let you pay weekly which might be a little easier to handle financially.

Hopefully your Mom will agree to let you have the money from your grandmother. I can't think of a better present than to help you be a great furmom.
