Fun fact - dogs have around 1700 taste buds compared to humans who have about 9000. Instead they rely on their nose to decide between the delicious and the disgusting.
So it makes sense that something like tripe - a stench akin to what I can only imagine, a rotting corpse - makes them go wild.
Lamb scores high on the deliciousness gauge while chicken is easy on digestion and apparently helps build lean muscle mass.
