alrite mate this may sound a bit stupid but i had the
same problem with my hands really painful they
were constantly cracking and bleeding because of the cold i think.
anyway mi mum got me this cream called AQUEOUS CREAM BP
this stuff is the bollock and really cheap about 1-2 pound for a big tube
this was the only thing that helped me it was solved within using
it about 3 times i tried vaseline etc didnt work.
should be how to pick up a tube in local chemist.
should work the same on dogs.
hope this helps
