Jondi and Atomic Betty helped us demonstrate dog intros recently. Intros are always a little different depending on the dogs that are involved, but a few key points are 1) take your time 2) praise any appropriate behavior 3) keep yourself happy and the dogs will read your confidence 5) keep it short and stay determined to set both dogs up for success and 6) end on a positive so the dogs walk away feeling good about their interaction.
I should spill that just before this intro, Jondi was busted for spitting obscenities at Betty through the fence. She avoids her a lot in this video, in part, because she got a scolding for that. The intro helped us end that bad day on a good note. We sure love us some Jondi.
