Apologies if this has been discussed before - any recommendations for a secure dog guard ? Unlike my previous CR-V & FR-V there seems to be no specific dog guard for this model. I have tried a Halfords one but it ain't up to my Staffordshire/Patterdale Crossbreed ? It has a flimsy plastic fastening to the headrest. If poss I wish to avoid the ones with poles from floor to roof which take up a lot of boot space.
