so sorry for your loss!!
and sorry if you were misunderstood and you got complaints. i am sure when you mentioned punishing your dog you did it humanely. some have an emotional response to these things and while i feel connected to anyone who loves animals, emotional responses sometimes don't get expressed very well in emails. obviously you love animals given your distress over the situation and you did your best. i have also lost a chicken to a dog and it is so hard to deal with the guilt. in my case, the coop was not dog proof (lesson learned). of course it had to be my favorite girl that was killed by the dog. and only a few weeks ago, a friends dog was visiting, and i spaced out and left my back door open while the girls were free ranging, when i realized it i ran outside and the dog had a mouthful of feathers - my heart sank and my nausea rose...but luckily it was only feathers and the chickens were fine. lesson learned - again.
so in memory of sweet pea, we can all remember to be super careful with our dogs / cats and other possible predators, and to try to be kind to each other, especially those who go the extra mile for animals, because none of us are perfect.
rest in peace, sweet pea.
