I'm so sorry.
Those poor pups. People treat animals like a disposable accessory. They should stick to fake pets on Facebook.
Of course, I love heelers, but they have too much energy for most owners. They are dogs that need a job or they will develop neurotic, maladaptive ways of releasing their energy.
It's also awful to put the dogs in a position where they become a threat to people and their animals. Around here, people think it's fine to let their dogs run loose to sow their wild oats. Then they start running in small packs, usually pairs. When strays have been seen in the yard, I have to look around carefully before taking the dog out, can't allow free ranging, and pretty much worry about the chickens in their pens for days...
It's a lovely day here. I'll be going back to work soon after the summer break, so I'm soaking up these last few days the best I can.
