We have three also, Chewy 4.5 yrs - 12 lbs - then came Choupette, 4 yrs - 8 lbs (Chewy was lonely) then I got Tucson who is now 3.5 yrs - 5 lbs (for me). They have their moments but all in all would not have any less. Love it. Walks are a bit more confusing, Chewy and Choupette are real pullers but Tucson who walks by our side really well gets pulled all over the place and has to run to keep up finds it somewhat exhausting. So I end up taking the two pullers and hubby gets to walk with Tucson. Quite the picture.
More work? yes but also a lot more fun
