Since the summer, Oberon has developed some new bad, rude habits. He barks when I'm on the phone, puts his paws up on the table when we're eating, and barks at our new refrigerator's icemaker. Nothing aggressive, just misbehaving and rude! This is in addition to his nonstop barking when the doorbell rings. He will stop barking when I'm on the phone if I throw treats for him, but I don't want him getting used to having treats all the time. I'm also pretty sure that the icemaker barking is because it makes noise, and he's pretty sensitive to machine-type noises. Bottom line is we've decided we need a session or two with an in-home trainer to work on these specific behaviors. I've talked to a couple, but am unsure as to how to figure out which would be best. Any hints or ideas on how to choose? Obviously we'll only go with someone who supports positive reinforcement (although saying no or ignoring him isn't something we're adverse to - as long as that's as negative as it gets). Other than that, though, how do we make the decision?
