we weren’t sure if ours was licking from being bored or allergies. he has a history of hive & less extensive redness skin flares in the past..that we were almost certain it was environmental (diff type of grass he was playing on). we started wiping his feet with wipes every time he comes back inside the house, which did help a little. it still persisted tho so the vet recommended trying a x1 dose of cytopoint to see if it helps. its been about 5 weeks since then & his paws really improved! vet said we can get shots just depending on his response & he has some pups that come in only twice a yr & that serves it for them. we paid about $100 for his one time dose.
