Thanks Sue - I will check those kennels out - I have never heard of one on the pear tree roundabout though. The lady down the road uses one out Aylesbury way - I can't remember the name but she said they are great with her springer - but nothing quite matches looking after a Monster, sorry Munster does it!
I am just going out to check on Tilly - walked her around again this afternoon when her owner came to see her and she seemed ok still then. Apparently she has had it before - bit greedy is what he said. Still was a huge worry for us and got quite fond of her already. I will check in again once I have seen her.
edited to add: just checked Tilly - stomach is making noises which is good I think - but no poos as far as I can tell - she has been standing under the willow tree all afternoon. Hope she is ok.
