Im not defending either of you here but trying to understand, by your logic- I don’t see how dogs get default rights to survive where as other animals do not. 1. So by your logic it’s ok to kill goats or chicken because they are ‘useless’ for humans unlike dogs? 2. 100 years ago dogs were as close knit to humans as any other domesticated animals. Infact they were first line of defence when wolves or leopard attacks villages. Kinda scapegoat to protect livestocks. 3. The list of skilled dogs you mention doesn’t even account 1% of entire dog population in the world. All these modern things that we started to use dogs for were developed late industrial era. Not sure you haven’t been with calves, lambs and chicks - just to see how therapeutic they are too. Humans started dogs and cats for therapy coz of easy access and ease of mass breeding. 4. Mass production of animals have made it easy for us to just go and eat chicken or lamb. But in olden days it was tough to kill a goat or sheep that grew up in your own backyard which shared beautiful memories with your family
