I think thats what I mean

As many of you know we have a Welsh Terrier ( 10 1/2 yrs now ) and were hopefully wanting to give a home to a rescue Wire Fox Terrier sometime next year. ( age and sex not important )
I have e-mailed the rehoming person for the WFT association a few days ago asking for information and told them a bit about us and how we live so that they had an idea of what we were like - don't know if this was the right way to do it or not!
One of the things that I was concerned , and a bit worried about is that we live in a flat. Does anyone know whether this will stop us being allowed to take on a rescue dog. We do have our own garden and take Rosie for walks and she is fine living here.
I suppose I was hoping that someone may have experience with this sort of area and could maybe give me some advice . The person hasn't replied yet so any help would be very much appreciated!
Thank you , Kate
