It's cold out there and you need to keep your dog busy since long walks are clearly not an option!
One of the first things I tell all my training clients is to give up their dog food bowls. They need things to do and simply putting their food in a dish does a disservice to you and your dog! There's loads of products out there that can make meal times interactive. Some of my favourites include Kong, Buster Cube and Tricky Treat Ball.
Start your day by splitting your dog's food into two portions. One half should be used for interactive toys which your dog can play with while you're at work. Imagine he/she is getting mental stimulation while you're not even home! Interactive toys are to dogs what books and puzzles are for people. The other half of their food should be used for training. Remember training doesn't have to be all stays and sits it can also be tricks like roll over and play dead. There are so many options out there when it comes to what you can train your pet to do.
Use their food to your advantage and have a happier, healthier dog as a result!
