What this means
Start by looking at whether your dog licks one paw or all four. A single licked paw more often means a local cause: a wedged thorn, a cut, an ingrown nail, inflammation between the toes, or pain higher up in a joint. Licking all four more often points at a broader skin condition such as allergy.
Second, look at the colour of the hair between the toes. In light-coated dogs, a spot licked constantly turns reddish or brown, and that shows fairly reliably how long this has been going on even if you never catch the licking itself. The skin between the toes may be red, damp, spotty or smelly.
Third, think about timing. Licking that worsens in particular months points at something in the environment. Licking that starts right after a walk points at something outdoors irritating the pads, from grass to road grit in winter. Licking in the evening when the house is quiet, or when left alone, may be tied to tension and boredom.
Fourth, do not forget the joints. Dogs sometimes lick the leg above a painful joint even when the paw itself is fine. If you also notice slower rising, reluctance on stairs or limping, mention it at the appointment.
Possible causes
These are things that can cause this sign. It is not a diagnosis, and they are not equally likely for your dog.
-
An allergic skin condition
Allergy frequently shows in the paws first. The pattern is licking all four while also scratching ears, armpits and belly.
-
A foreign object or wound between the toes
A thorn, a grass seed, a cut pad or an ingrown nail causes persistent licking of one paw. The dog may pull the paw away when you try to look.
-
Skin infection between the toes
Bacteria or yeast multiply in the damp area between the toes. The skin reddens, a smell appears, and the surrounding hair turns brown.
About the condition: Skin infections -
Irritation from outdoors
Road grit in winter, hot pavement in summer or lawn chemicals irritate the pads. The licking then starts the moment you get home from a walk.
-
Joint pain
A dog may lick the leg above a painful joint even when the paw itself is healthy. Slower rising or reluctance on stairs often go with it.
-
Tension, boredom or habit
When licking becomes a self-soothing habit it repeats on quiet evenings or when the dog is left alone. The skin is damaged over time, so inflammation joins in.
What else to watch for
These observations help your vet build the picture faster. Note down what you saw and when.
- Whether one paw is licked or all four
- Whether the hair between the toes has turned red or brown
- Whether the skin between the toes is damp or smells
- Whether there is a thorn, wound or ingrown nail
- Whether the licking ties to a season or to walks
- Whether your dog rises more slowly or avoids stairs
When to book a routine visit
Book a visit if the licking carries on for more than a week, if the skin between the toes is red, damp or smelly, if the hair has changed colour, or if your dog is limping too. Mention whether the licking ties to a season or to walks.
Related conditions
Conditions whose entries mention this sign. The list is somewhere to read on, not a way to reach a diagnosis.
- Allergies (food, skin and environmental) Skin and coat An allergy is an overreaction of the immune system to substances that are essentially harmless, such as pollen, house dust mites, moulds, flea saliva or an ingredient in food. In dogs it shows up mainly in the skin and ears, and constant itching wears a dog down and can open the way to skin infections. More than one trigger can be involved at once, so finding the cause takes patience.
- Atopic dermatitis Skin and coat Atopic dermatitis is a long-term allergic skin disease driven by an inherited tendency: the skin overreacts to environmental allergens such as pollen, house dust mites or moulds. These dogs have a weaker skin barrier, so allergens get in more easily, and scratching irritates the skin even further. Signs can begin in young dogs and, depending on the allergen, may flare up at certain times of year.
- Pododermatitis (inflamed paws) Skin and coat Pododermatitis is inflammation of the skin of the paws, affecting the skin between the toes, the pads or the skin around the nails. It is not a disease in itself but a sign that something is wrong: allergies, bacterial or fungal infections, parasites, a trapped foreign body such as a grass seed, hormonal disorders or other illnesses can all cause it. Because there are so many possible causes and sore paws make walking hard, finding the cause is a job for a vet.
- Skin infections Skin and coat Skin infections are caused by bacteria or yeast that start to multiply when the skin's defences are weakened, for example by an allergy, parasites, moisture trapped in skin folds or constant scratching. An infection can stay on the surface or reach the deeper layers of the skin, causing pain and intense itching. What caused the infection and what keeps it going is for a vet to work out.
- Arthritis Bones and joints Arthritis is inflammation of the joints in which the cartilage gradually wears down, leaving the joint stiff and painful. It can develop with age, after an injury or because of joints that did not form properly. Ongoing pain limits how freely and comfortably a dog moves, so changes are worth showing to a vet.
- Anxiety General health Anxiety is a state in which a dog feels tension and fear constantly or far too strongly, even when there is no real danger. It can be set off by being left alone, loud noises, new surroundings or strangers, and long-lasting anxiety wears down both the dog and the whole household. It helps to understand that this behaviour is not stubbornness or disobedience but a sign that the dog is struggling.
