I can't speak to your observation Teresa. I grew up on a farm with lots of animals... but typically only one (never more than 2) herd dogs at any given time. Always outdoors animals and never psycho barkers. However farm dogs are working animals who are purely in love with their jobs... but if they can't go to 'work' each and every day they will get kinda nutty... depressed even.
These particular neighbor dogs are basically happy, beloved, inside dogs. But this morning I really watched what happens outside...
1) The two dogs, one male and one female, I have 'assumed' to be litter mates... but I don't really know. They 'feed' each others barking in a competitive bid for Human Mama's (or sitter's) attention.
2) Mama IS a good heart. She nearly always keeps the babies with her; takes them with her to work during the day... then outside to play, exercise, and keep her company at home.
Here's the but: while outside, she's multi-tasking (or thinks she is) by talking on the phone... and throwing their dog toys. Doggies fetch & bring the toys back to her... she is distracted with her business on the phone (oops NOT multi-tasking)... so they bark-bark-bark-bark-bark... until... she finally 'rewards' their barking by throwing the toy again. Rinse & Repeat.
It's the myth of modern multi-tasking: fractionally-there, not fully present/focused with ANYTHING or ANYBODY. The all too familiar, modern style of simultaneous ABSENCE on multiple planes of reality. Like something Sunspotbaby posted about parents so busy on their cell phones they can't even hang up when picking up their child from the day caregiver.
3) So. I believe neighbor tries, with every good intention, to be a loving attentive mama... but despite that loving intention, the action is ever so slightly askew... and unintentionally ends up rewarding the furry babies for inappropriate behavior that is rooted in HER OWN compliance with modern societal mores & distractions.
4) Then... 'society' (aka DuneAHH) complains and the babies get sent to prison (aka taken into the house) with no understanding of why, when they'd been having such a good time getting rewarded for fetching and bark-bark-barking.
Well Thanks All! This has been good therapy for me. Now I have an actionable vision for Hilary's 'It takes a Village working together to raise a... good dog' (and I won't have to resort to becoming the next new obnoxious neighbor with an air horn ;-))
