Do you have any cheats for how to get more money with out selling things?

You could also go around to every plain tree and shake them. Sometimes a sack with a 100
bells will fall out.

Another way is with the golden shovel hit every rock in town with the shovel once a day
and if you hit a certain rock a bag with bells in it falls out!! I forget how much there
is in it but who cares?

Is it possible to get a dog? I have heard lots of different ways but i never succeded i
have one chance left but it will take a long time.

To be truthful i am not to sure but you should look up more ways to get a dog and try each
one. I tried someways before and they didn't work. I think some people glitch their game
to get a dog, but if you really want one try multiple ways and tell me your result.

Hope this helps!! ~shinyskitty~
