Those avacado studies come from Horses & Parrots having toxic reactions. When you think about how either would eat an avacado it makes sence. My Rotty & the Malamute(RIP) would split 1(one) avacado over two or three meals in thier barf mix. So that would be an 1/8 to 1/4 avacado per serving to a 75 & 112lbs dog. So yes, one must keep perspective. I give garlic occassionally also with no observed ill effects. When feedig BARF/Raw varity it the key point.
