My two dogs love the Klimb. When administering treats, both dogs would bark relentlessly fighting for each treat
Now, Iwalk over to the Klinb, they jump on it and sit QUIETLY as I pass them out. It only took a day or two. Basically, when they are on the Klimb and barking, I turn my back on them until they stop. Now, they jump on the Klimb and sit quietly. I count to 5 and hand over the treats. The Klimb is there 'quiet place'.
