Sat waiting to take our 19 year old to the vets.
Took her to vets on Wednesday as she had blood in her poo and they found a lump but wasn't sure if it was just poo that hadn't moved along as her muscles are going so she is booked on again on Wednesday for another check to see if it's gone or if it's a tumour. She had an injection and was sent home.
Come down this morning to bright red blood all in the hall, living room and kitchen and her backend covered in it. She's walking and cleaning her self and just got up for some water and had some food but she's walking with her tail slightly lifted like they do when they are going to the toilet.
Meeting vet at 8am and hoping that it's nothing sinister, just a blockage. Lost our 18 year old 11 days ago to renal failure and not ready to make that decision again even though I know she's a good age 
Any experience anyone with something similar?
