I currently own a 2 year female pure bred pit bull that is the nicest dog in the world. She is very affectionate and loves to be around people. One of my roommates really wants to get a chihuahua puppy. I have pet-sit for another chihuahuas before to see if it could work and there was no issues even when they thought they were alone. There will be times during the day when nobody will be home but she plans to crate train her dog in her room. Do you think there will be issues with this arrangement? Or have any insight on how to make this work?
