Hello all
We have been thinking about getting a dog for around 2 years, but decided to wait till our boys were a bit older. They are now 6 and nearly 8 and we think it may be the right time. 
We have a smallish house with a garden and a field 2 mins away. The dog would have two walks a day plus any extra - we don't have a car so walk a lot, so it could come back and forth to school etc.
We have a house rabbit who has run of the dining room so would need to take that into consideration.
It would need to be easy to train as I would like it to come everywhere with us including on the train.
I would love a big dog (have always had a yearning for an Old English Sheepdog) but realise that might not be such a good idea in a small house.
I have done some research but not really getting anywhere.
Any suggestions and advice would be very gratefully received
Many thanks in advance
