The 2014 thread on the OED etymology includes much about ***@English.
I will put my own opinion here.
***@English = dog/gudaga/***@Mbabaram(Queensland, Austl).
It is claimed generally that these two are not cognates but coincidences.
My claim is that they evolved in parallel from an older form, approximately
*qu(d)ongca. Speculative source of dog domestication: Phu Quoc island, Viet Nam, near Sihanoukville, Cambodia, before 15ka, by indigenes, and were bred for pulling small bowl-boats(***@India/***@India/***@Welsh) between island and mainland at first, initially with hands holding the mane-ruff and tail, eventually selective breeding producing the ("Rhodesian" & Phu Quoc) ridgeback dog along with other types of dogs throughout South East Asia.
***@KhoiKhoi:ridgeback hunting dog
***@Cree:animal that pulls
***@Spanish:dog ~1ka from carry/ferry?, brought by Visigoths from Morocco Atlas mountains? The Amazigt Berbers of that area use 5 dogs to hunt, 4 bite the 4 heels to stop prey, one clamps down on the throat to kill.
*qu(d)ongca may have become donkey in reference to load carrying in dry climes?
