A swan which was viciously attacked by a dog had to be put down - after suffering 'severe' injuries.
Shocking pictures of the bloody swan revealed the extent of the majestic animal's injuries after it was mauled by the animal.
It had significant puncture wounds under both wings and was bleeding from the mouth when it was rescued by animal welfare officers.
Passers-by who found the swan after the attack, in Victoria Park, Glasgow , on May 24, rushed to call the Scottish SPCA.
Sadly the animal had to be put to sleep and the animal welfare charity is now urging dog owners to keep their pets on a lead around swans.
Scottish SPCA animal rescue officer, Aidan McIver, said: "We were alerted to the injured swan in Victoria Park in Glasgow on 24 May.
"A concerned member of the public had contacted us after finding the bird with significant puncture wounds under both wings and bleeding from the mouth.
"He was also unable to walk on his right leg.
"The injuries were consistent with a dog attack.
"The swan would have experienced immense pain and suffering due to the severity of the wounds.
"After seeking veterinary advice, the sad decision was made to put the swan to sleep.
"This is a stark reminder to dog owners to keep their dogs on a lead around swans, and all wildlife, at all times."
The Scottish SPCA has been alerted to a number of incidents across Scotland where a swan has been injured, killed or humanely put to sleep as a result of a dog attack.
Earlier this month, a swan sustained serious injuries at Straiton Pond Nature Reserve in Midlothian.
