I dont plan on getting another dog any time soon but am preparing for the possibility. Dh would like something a bit smaller. Pug size maybe. Who knows when... Could be a few years from now. But since the topic came up here at home I have been wondering about size comparisons. Does anyone here have any info/experience with smaller dogs? for instance, do you have a gsd and a boston terrier or pug sized dog? Can the smaller dog hold its own? Do they play well? Do you think its all about attitude of the dogs and training? Can your smaller dog go on super long walks or do you have to call it quits earlier for the smaller one? Supervision is a must as well I would imagine. Thanks in advance.
