He also has OCD like Peanut, he'll lick his paws. My vet said some dogs lick their paws, it's just like thumb sucking lolll! He's had skin scraping/cytology done & all they found was some normal bacteria they pick up from the ground/grass (some cases it can be yeast bacteria that causes the frito feet smell). He prescribed some spray (can't remember what it's called), but I didn't like that Momo was still licking & possibly ingesting the medication.
I've been using Warren London's Sani-Paw as a cleanser after their walks & he's stopped licking his paws.
