My two dogs are terrified of them, which is funny cause the dogs are huge, yet they whimper away whenever I move them.
Ha, Ha , Ha...got to love the big sissy dogs.... One of mine is a very lean 100 lbs (still to fill out). He's afraid of the "glug" the water jug makes. Got it for him because he thought his water pail was a mini swimming pool for those hot days. He's not terrified of the bikes, but he regard them with deep respect.
