Hunter Gatherer

We have a Doberman named, Dobie. He is about 9 months old. When our grandsons visit, they love to play in the stream next to the house and catch frogs, minnows, etc. When they catch them, they put them in a pail for awhile and then put them back in the stream.
Dobie is always with them and I guess he decided he needed a pet as well. So far he has carried — without harming it – three frogs, and put them in his water pail. He only puts in one at a time. So far, I have not seen him doing this. I only see the frog in the pail. My grandsons live six hours away so maybe he is collecting the frog for them to save them time? –
