THE RSPCA has launched an investigation after a dying puppy was found dumped in two sealed-up plastic bags in a remote spot in West Yorkshire.

The three-week-old chihuahua-cross puppy was found on Monday in Bank Wood Road, Darrington, near Pontefract, at 1.30pm by a female passerby.

She initially thought the pet had died as he was cold and unresponsive.

However, once in her car, the black and white pup began to warm up and show signs of life.

Despite the best efforts of the veterinary staff - the puppy became unresponsive and sadly the vet made the decision to put the pet to sleep to end his suffering.

RSPCA Animal Rescue Officer Ollie Wilkes said: “This poor pup was discarded like a piece of rubbish in a sealed-up bag and it was so lucky he did not suffocate.

"I am keen to find the callous person who did this and left him to die alone at the side of a road.

“I have no idea why anyone would do such a vile act - perhaps he was an unwanted puppy in a litter - but to leave him like this is abhorrent. 

“I am appealing with information to contact the RSPCA on 0300 123 8018.”
