Back here in england, my friend found on our beach which is only minutes from my house, a handfull of cheese cubes with nails inside them, people can be so cruel!!
Underscores the importance of teaching "leave it" & of keeping a dog leashed even at a dog park. Or at least until you've checked out the area. How sad.
THANKS for posting this! I just forwarded to the Facebook group for my local dog park! You never know, there are some sick, whacked out people out there...
