Help Jessie The Labrador

Jessie our 4 yr old Labrador needs an operation to remove a lump she has developed. We don't have any insurance to cover as we have not had the spare fund's to pay each month. Now our beloved loyal baby is unwell and now we have no way to pay for her urgent treatment. The sooner she can get the surgery she needs the better chance she has to prevent further complications.
We have a small amount we had  saved for a holiday we planned to take in a couple of months which now due to this terrible news we have cancelled and put the full amount towards her surgery. But even this barely dents the amount needed, we are going to add as much as possible from our wages each payday but this will take sometime. If anyone can help with whatever they can spare to accelerate our own efforts Jessie and most of all we would be eternally grateful.
