I was stuck on 11a , could see that 'porky' is a lie - which is a 'tale' - and also had done all the rest of the clues so had T - L - looking at me , and could not see a better alternative than 'TALE'
However the 'dog needs to be picked up' bit as explained by mamya is still puzzling me and I would appreciate a bit more help with the parsing. Thanks in advance !
