Having done a fair amount of research on these two breeds I am not sure which of these is best suited to life in a busy house (with 4 boys aged 5-9). I am looking for a loyal companion who is happy to walk in the park and sit with me whilst I work during school hours but who won't be too agitated by the after school activity!

Our previous dog, who sadly died recently, was a greyhound.

Any advice would be much appreciated!
