please help i have a 15mth staffordshire bull terrier and he keeps licking his feet and making the pads sore what can i do to help or to stop him as he licks them hat much they go red

He needs to see a vet - sore paws can be caused by a mite or fungal infection, or he may be licking them as a reaction to pain some where else in his body - like impacted anal glands....
