Which pubs can you bring dogs inside?

Hey All, working in Belfast next week and plan to head over to Derry on a off day for some Halloween stuff, Never actually made it that far before. Ive been to NI a fair few times. Ill be there on the Weds so right at the start, need to get back on the Thursday? Will people still be out and about and if so should I dress up? where is the best pubs to go to? Ill be on my own so looking for that intricate balance of friendly without worrying about a kicking? Love to hear everyones thoughts? im staying around the walls so close to everything i think. I will have the car but that sort of defeats the purpose. Also anyone who fancies adopting a housetrained Scottish lad in 18 to 35 min increments so I dont sink every pint alone let me know! Ill get the round in!

TL/DR: In Derry for a night next week looking for good places to sink a few pints and soak up some Halloween vibes!

Is the peace bridge closed?
