Any advice? 
We have recently moved to a house which is further out in the country than we were before. There is decking in the a garden and there is small hole under it - which the the dog managed to get in today.
He is an 18 month old spaniel and has a good recall - apart from when he gets a scent of something and digs madly. DS heard “scuttling” under there when he saw the dog go in.
He has been in there for about 20 mins and he just barking constantly - I am worried he is fighting with rats
I don’t think he is trapped, just choosing not to come out.
We have tried treats and calling him. It is a rented house so we cannot do anything to the decking to retrieve him. Starting to panic about him a bit...
