Looking for a s/c suitable for 2 families anywhere between Bristol and London

[BettyButterknife]

Anyone got any tips? Other criteria are:
dog friendly
available for the first weekend of November (long weekend, last bit of half term)
Not completely outrageously pricey

We will be 4 adults, 4 kids and a baby.

have a look at petswelcome website, dogfriendly website and lastminute-cottages websites and you should find something there. it is finding the dog friendly that will be the trickiest bit. most places wont take a dog under 1 either so hope its not a puppy. sure you will find something on one of these.
