There have been tiny Yorkies here in Scotland killed by crows and seagulls when outside, as well as one horrible Postman who kicked a tiny one, lifting it with the toe of his boot as it flung in the air, giving it head injuries. It was a 4 year old's pet, and she and her family were inconsolable.
(The Postman got sentenced for cruelty.)
Not to mention all the horrible people who look for pedigree dogs, especially tiny ones, to dogknap or steal and sell on.
Not to mention the weather !
Not to mention that these dogs need watching and a lot of careful attention.
Not to mention any other animal/bird which could attack and kill such a tiny deffenceless animal.
................ETC.ETC.ETC.
Is this an April fool ?
