Short answer: Mostly it’s the salt and skin chemistry – your feet are the saltiest, most scent-rich part of your body for a dog. Feet also accumulate interesting environmental smells. Occasional foot-licking is normal; obsessive nightly foot-licking can indicate anxiety or compulsive behavior.
What you should actually do
- Sweat glands on feet make them salty and aromatically interesting – dogs are particularly drawn to sodium chloride.
- Feet are heavily colonized with skin microbiome organisms that produce volatile organic compounds – irresistible to a nose that has 10,000x our olfactory sensitivity.
- It can also be a soothing/self-regulating behavior – some dogs lick feet during stress or pre-sleep ritual.
- Compulsive foot-licking (your feet or theirs) can be OCD-spectrum – more common in GSDs, Goldens, and Dobermans.
- Avoid letting dogs lick recent open cuts, fresh tattoos, or after foot creams/medications.
If foot-licking is part of a cuddle routine, it’s a bonding behavior and harmless. If it’s accompanied by other anxious behaviors (pacing, panting, pawing) or has become obsessive, treat it like any other repetitive behavior – redirect with a Kong or puzzle, increase exercise, consider behavioral evaluation.
After putting on hand or foot lotion, give it 15 minutes to absorb before letting your dog lick – many lotions contain xylitol, zinc oxide, or other ingredients that cause mild GI upset or worse in dogs.
