Thank you for your questions.
It is both feet, and he is creating a sore spot where he is licking. One foot is worse than the other.
There was no improvement when he was taking the medication that the vet prescribed. That is why I consulted you.
He has only started licking about a month ago. He hasn't done it before at any other time of the year.
His front legs aren't twisted and his feet doesn't turn sideways, and his toes do not sply.
He is a little overweight, but not a lot.
Since I consulted you we have MORE PROBLEMS. He doesn't seem well in himself. He seems unhappy, and keeps finding quiet places to lie down. Though he is still eating, and chasing birds in the garden!!
His coat is a little dull - not as shiny as usual.
One of his eyes has now started to "run", and I found a tiny bit of yellow pus in the corner.
