Hey Blessings,

I'm certainly no expert on dogs though I do have a big dog who loves people.

I love dogs tremendously but when there's more than one you always have to be careful. They are like a kid in a gang, they do stuff they would never do alone.

And the whistle sounds like a great idea...I can't see a dog wanting to be near that sound.

Even my people loving dog will almost knock us down sometimes just out of playfullness.
