The surviving lighter coloured male puppy has been named Piglet, he has an abscess on his back leg, which is currently being treated with medication and daily dressing changes. Piglet also appears to have chewed ear tips, a minor umbilical hernia and some fur loss, possibly as a result of mange.
Piglet is being cared for by Wiltshire dog warden staff at Hillcrest Kennels in Coombe Bissett, near Salisbury, where he has already been offered a home by a member of staff.
RSPCA Inspector Patrick Bailey, who is investigating, said:
"It was very lucky that even one of the puppies survived, having been dumped so callously.
The suffering of the puppy found with ruptured eyeballs does not even bare thinking about and his littermate was not in a much better state.
I would urge anyone with any information about where these puppies came from or have information about them being abandoned to contact the RSPCA so we can ensure there are no other animals in the home being allowed to suffer."
