I know some of you are probably wondering what the records you find during a walk right? Well, I don't have them all but I have a full set of one catagory of records, and I'll tell you some of the things I experienced when I played the records. Though some of them don't do anything.

"Growler" - Nothing, just music with dog barks every so often, sort of chase type music
"Smilin' Dog" - All I've found is that your dogssit infront of you when the music plays and if you touch anywhere on the screen but on the record, your dog will move its head according to where you touch. Note: It doesn't work on sleeping dogs
"Friendly Wiff" - Nothin much, your dog may sit though when they hear the tune
"Surprise" - At first the music will play slow, then it will make a really loud sound and your dogs will jump
"Naptime" - Your dogs will yawn and lay down as the musiv plays and they'll go to sleep, but they may not stay that way
"Colonel Bogey" - Your dogs will follow eachother in a line around the room and depending on how you adjust the speed, your dogs will walk or run
"Treador" - Your dogs will growl when it plays and start attacking eachother, and when you call them they'll turn around with their but towards you and look like their digging with their hind legs or back up and bark. If they get close to you them may bite
"Flower Waltz" - Your dogs will dance at cirten moments in the song
"Nintendogs" - Your dogs will sit infront of you and bark the song when it comes to a cirten part

There are many other records you can find besides these that will affect your dogs in many ways, experiment, watch, laugh. Have fun with both you and your dogs! Hope this helps! ^^
