Assistance dog co~op

I’ve had an assistance dog for 12 yrs with me in the co op no problem, I lost him this the start of this year, my daughter found me a pup to become my assistance dog and went in no problem a month ago an email had gone round banning me from taking her in, she has the lead and jacket explaining who she is I’ve done the disability act 2010 but still refusing me, my dog is super quiet in shops and not interested in bother people or eating the food all other shops cafes and takeaways are more than happy to have her in their establishments I now have to travel further to get any items I may need which I usually get bread milk etc in the co op. My furry is there for severe anxiety and depression and the co op have made it worse 😢 it’s not like she’s a giant breed (see photo)
