We have bought a trailer for the bike to put our dog in but he won't go in! When we did get him in and attached him with a lead, he jumped out and was hanging out of the trailer. Clearly he doesn't like it. We have now taken wheels off and leaving it in the room he sleeps in next to the kitchen and coaxing him in with bit of cheese etc. The question is, will we ever get him in it with the wheels on and attached to the bike? Has anyone else had to train their dog up to use the trailer? Any tips most welcome. We go away next week and were hoping to use this rather than leave him in the motorhome. He is 2 and a half and a working cocker spaniel.
