I once had a Jack Russell terrier named Sugar (he was white with a brown head and brown spots) who often smelled like corn chips.

Rotten socks! She is a Rottweiler. 

My sister always says that her dog's paws smells like Doritos Chips. Funny that you think the same as her haha !

Suri - a desexed female tabby cat - has only the faintest cat smell most of the time,
but just after meals her breath smells of fish or steak.

The horses have their unique horse smell - the best I can describe it is slightly like nutmeg,
with urine that smells like new-mown hay, and poo that smells like fermented grass.

My little cat was born with a bad tummy.  So when he gives kitty kisses or has gas, he smells like rotten eggs mixed with stale vomit.

My little dog never seems to have a discernable odor, despite infrequent bathing. I presume it's due to genetics and overall good health (knock wood). 

My bigger dog is a bit more stinky, particularly on rainy days. I clean her ears and use wipes and cologne between her regular grooming appointments if I think she smells like corn chips and/or beer.  I believe it's due to yeast overgrowth, by the way. 

My cat? A pussy, of course.
