More than 4,000 animals were abandoned across England and Wales- almost 700 of these were animals dumped in the Midlands last Christmas.
The charity say it is already caring for many animals abandoned around the country this festive season.
Number of animals abandoned in the East Midlands last Christmas:
A member of the public found the thin female dog in Whitcroft Lane and contacted the RSPCA.
She was taken to the vets where she was found to be underweight and overbred. She also needed treatment for a dry skin condition and was not microchipped.
Oola is now in the care of RSPCA Leicestershire where she will stay until she is fully recovered.
Number of animals abandoned in the West Midlands last Christmas:
Nelly was abandoned in a water-filled ditched on 10 December and had to have her leg removed after she contracted an infection.
She was discovered abandoned and terrified by a dog walker in Clevedon Road, Balsall Heath, Birmingham.
The Staffordshire bull terrier-type dog was left tied up with a martial arts belt with a severely injured and infected paw.
The RSPCA are urging people to help them care for the animals spending Christmas in their centres and hospitals with their Stock the Sleigh campaign.
The charity need donations to provide food, medicine, treats, toys and warm blankets.
