I have narrowed it down to the top four breads of dog...
1) American Bulldog...very good with kids, don't need a lot of exercise, they are good guard dog, and they look tough.
2) Pug...they are good with kids, funny looking, social, small in size, and don't need a ton of exercise.
3) Dachshund (aka Wiener dog)...I think these dogs are some of the cutest dogs, they are great with kids, good guard dogs despite their size, small in size, and curious.
4) Miniature Pincher...good gaurd dogs despite their size, good with kids, social.
