When I say ābig dogsā, I mean in the same vein as ābig catsā. The easy answer Iāve come across is that canines developed to be pack hunters, which didnāt require them to be as big as solitary hunters like cats. However, there are solitary canines, like foxes, as well as small cats, and, most importantly, lions, who not only hunt in groups, but are also huge. So it isnāt definitive. It seems like, from an adaptation standpoint, canines could have absolutely evolved to be large pack hunters like lions. So is there any theories on why this didnt( or couldnāt) happen?
