Tinkerbell is my Yorkie and I also have a maltese, the problem is that I have always kept Chiquito in an X-pen and Tinkerbell has always stayed out FREE, meaning she gets to be out all the time. Chiquito is a little over 6 months and he is not completely potty trained as for Tinkerbell she is about 95% potty trained. When I got her she was 6 weeks old and just so tiny that I was afraid to "cage" her. The problem is that she feels the house is hers, everytime we let Chiquito out to play, she attacks him if he even gets near any of us or touches any toys, when it comes to snack time she will hide hers and wont let Chiquito eat his

. What can I do to make Tinkerbell not attack so possesive of the house?
