A tiny puppy who was "dumped in a rucksack" in Berkshire woods is now safe with the RSPCA, after witnesses saw a man abandon him and run off.
It's suspected the chocolate cockapoo was neglected due to health problems, as he "seemed unable to use his back legs".
The RSPCA is appealing for information about the eight-week-old puppy - now named Watson - and the person who deserted him in Finchampstead Woods.
Inspector Andy Eddy, who is investigating, said: "Times are hard and we appreciate that pet ownership and vet bills can be expensive but it is never acceptable to abandon an animal, particularly one who is sick and vulnerable like poor Watson."

The little curly-haired puppy was rushed into a local surgery on 10 February after walkers found him in a "collapsed state" and reported the incident to the RSPCA.
Inspector Eddy said: "Witnesses had been walking through the woods when they saw a man dump the bag - a black Reebok rucksack - before running off.
"Vets initially had concerns as the puppy didn't appear to be able to use his rear legs and they suspected a neurological problem.
"However, they've run numerous tests and have been unable to come to a conclusion as to what is making him unsteady on his back legs.
"He's got stronger and is improving every day. He's now bright and bouncy, and his mobility is much better.
"He can be weak on his rear end and has some strange episodes where he appears to go a little vacant so this will be monitored.
"I believe he may have been abandoned due to his health problems.
"Perhaps a breeder felt they'd be unable to sell him, or perhaps an owner was concerned about the cost of veterinary treatment.
"Either way, I'm looking into the circumstances and would be keen to speak to anyone who saw the incident or who may know who is responsible to call us on 0300 123 8018."
The man was described wearing a black and white t-shirt, jeans and a baseball cap, and was speaking in a foreign language.
Watson has been moved to Millbrook Animal Rescue Centre in Surrey, where he'll be fostered by a member of staff and continue to be closely monitored.
Watson is not yet available for rehoming. Please do not contact Millbrook to enquire about him as you may block the phone lines and prevent an emergency call from coming in.
