Those are good precautions i really like them.... Well that is good that they get along it was a hard tryin to get my male pit along wth my smallest chihuahua because they were both male....but now they cant even be apart they are always layin next to eachother on the bed or playing with eachother......it is kinda adorable because he is a lil tiny chihuahua and he is a 130llb pitbull and dozer will roll over for him........
