Killer-Diller
Border Terrier - Wikipedia, the free encyclopedia
You can't go wrong. Brilliant with kids. Small enough to be convenient. Big enough not to look stupid [see Chihuahua etc]. Sh*t easily manageable to pick up in nappy sacks; not like the camel sized portion a labrador produces.
Got two of them and they are GREAT. Like any dog though, invest in a few training classes for them.
