Dog owners are being urged to keep control of their pets after horrific attacks that led to two swans being put to sleep.
We was left with severe injuries and was put down after being mauled in Glasgow's Victoria Park.
And the Scottish SPCA have now revealed another bird, this time in Midlothian near Edinburgh , was also put down after a vicious attack.
Shocking pictures of the bloody swan in Glasgow revealed the extent of the majestic animal's injuries after it was mauled by the dog on May 24.
It had significant puncture wounds under both wings and was bleeding from the mouth when it was rescued by animal welfare officers.
In a similar incident, the animal welfare charity were alerted to Staiton Pond Nature Reserve where a swan was found badly hurt on April 30 with "injuries consistent with a dog attack".
A member of the public contacted the Scottish SPCA after seeing it injured and unable to walk on its right leg.
Charity chief inspector Paul Anderson said: "The caller was worried the swan was out of the water and sitting in an area popular with people and dogs, and was making no effort to protect his mate.
"Despite a number of attempts by our animal rescue officers, they were unable to contain the swan. After securing a boat to aid our efforts, we managed to catch him."
He added: "The swan was immediately taken to our National Wildlife Centre and vets concluded the wing injury had been caused by a dog bite which could have been treated.
"Of greater concern to the vets was a badly arthritic leg that had become infected. This wound and condition was deemed un-treatable and in the interests of the bird's welfare, the difficult decision was made to put him to sleep.
"This condition meant he wouldn't have been able to survive in the wild as he wouldn't have been able to get in and out of the water, fly and evade danger."
The Scottish SPCA say they have been made aware of a number of incidents in which swans have been injured or killed due to dog attacks.
Chief inspector Anderson added: "It could have been the leg injury that made the swan an easy target for the dog in the first place.
"The swan would have experienced immense pain and suffering due to the severity of the dog attack wounds.
"This is a stark reminder to dog owners to keep their dogs on a lead around swans, and all wildlife, at all times."
Anyone with information about either incident is urged to contact the Scottish SPCA animal helpline on 03000 999 999.
