My Dog Has One Lump Ontop Of His Paw Between The Toes, One Between His Pads Under The Paw And Another Under His Paw On The Part He Doesnt Walk On, Past His Pad. All Of The Lumps Have Developed Additional Blood Blisters Ontop Of The Lumps Which Burst Every Week Or So Then Rise Again. My Vet Seems Stumped As We Have Tried Every Type Of Anti Inflammatory, And Antibiotic Going And Nothing Seems To Be Affecting It. He Has Had Swabs Taken Which Dont Show Anything So We Know It's Not Cancerous And I Am Bathing It In Salty Water 3 Times A Day. Any Ideas?

More diagnostic testing needs to be done.  Your dog needs to have x-rays taken to rule out bony involvement.  A skin biopsy should be done on these lumps and sent out to the lab for analysis--this will tell you exactly what is going on.  Also a bacterial culture should be performed to make sure this is not a resistant bacterial infection (MRSA is becoming more common in pets).  A fungal culture needs to be performed--this could be fungal in origin.
If your veterinarian does not feel comfortable managing this case they can refer you to a veterinary internal medicine or dermatology specialist.

I flagged this a while back because my dog had the same problem. She went through 2 surgeries at her local vet before being referred to someone who regularly operates on dogs who have cancer and could take the ENTIRE mass out. Once every last piece of the mass was removed we have been in the clear for 5 months now!!! That's the longest she has gone without it reappearing. We have dealt with this for over a year now so that is huge progress. They said it was a bursitis which could be where her hair was growing back into her skin or it could have been a pore that was clogged. They weren't sure but she was tested for cancer and everything under the sun twice and it all was negative.
