You have a minor misspelling in the following sentence:
We never let our dogs out (Partly true, this is due to 1, our mental and physical health, but more so due to the neighbours not maintaining their fencing - which according to the council and housing association is their responsibility, we are not even allowed to touch it - and therefor we have to let the dog out on a lead in our back garden as we dont want them to jump the fence).It should be therefore instead of therefor.
