Oh rose how horrible for your poor dog- and you. If youre a softie like me it is very upsetting as your pets are a huge part of your family. Anyway, my sons dog has been gnawing at his paws for months now- they are constantly sore and bleeding- the vet seems to think its a bit like nail biting- a remembered response to a hot spot- so she prescribed some foul tasting stuff to spray on so he will not want to bite at that part again. I daresay youve tried that thouh. My cat seems to be suffering the same- although it seemed to clear up so we were really happy.

I then had a small operation and my head was everywhere since August so I forget to put his flea/ tic treatment on his neck during that time-(Frontline,) and then he was biting his rear 'hock' so they bled again. All I can think is that he is allergic to fleas or ticks as it seems to have settled down although his hocks are red and sore poor little puss.
It seems to be a fairly common problem though so good luck and I hope your dog soon gets better.
(off the subject here a bit- my very old cat who is no longer with us was lying on his back one day- I looked and thought I saw a tic on his lower abdomen- Oh!!! I thought and I tried to remove it - only to discover- horror of horrors that it was his penis!!!!) Well, you live and learn.I swear the old cat was smiling. God bless him.
