Oyr Blue Heeler dog loves to play in the pool with the kids. They throw it to him and he promptly bounces it back to them. Dogs are part of the family just like the children. They all should be allowed to interact with them.
Having said that you still have to be very wary that they do not bite anyone. Never let a dog near your face.
This same dog in the video, give the kids a little nip (no not a bite) he just snaps his mouth. In otherwords he is telling the kids that he has had enough.
We should all take notice of the signs that our pets give out. Maybe then people would be less likely to be bitten. This is not always the case though.
