wow thats nice that you noticed i was gone..i've been busy lately & in my free time..well there is none especially since maisy began chewing up wee wee pads and discovering new thingst o get into it seems like theres always something to clean up!!!!!! well i did buy maisy a bo-bo and she loves it! she knows exactly the right spot to bite so that it will make that noise!! on the pets mart commercial they call it bo-bo so thats probably why your instructor calls it that! thanks for all thesuggestions!!!
