Double pushchair reccomendations??

Georgia

By the time my baby is born my youngest will be 1 year 4 months /5 months.. my first thought was a single with a side seat but I'm put off the idea because I have 2 husky pups that have to be on long walks who like walking at the side of the buggy of my youngest.. one on each side like they protect the pushchair I don't wanna deviate them from that as that's what they have been use to since we got them.
