dogs licking thier feet

Years ago one of our dogs used to lick his paws until they were sore. The vet advised that it was due to too rich a diet. He advised feeding him on 'Chappie' dog food which was the cheapest available at that time. I can't remember if it worked or not.

hes still doing it but not as bad thankfully ,i really reckon its got something to do with the cold grass and frost  as he never done it before 

buddy my jack russell is doing it on and of as well , i wanted to go in the hottub but jack has to be out there as well as he thinks its great fun to play at the same time i want him of the snow i wont be walking them for a few days so they will just have to cope with it .
