If you come home one day after work and find that your table or sofa has been chewed up, calm down. The only person should blame is you, because this is essentially a cry out for help. Dogs that are locked in the home for the majority of the day will feel trapped and even though they might look calm, certain trigger actions will show their angst.
Double the fun
A simple game you can play at home is the three cup treat. It's a easy as it sounds, because you get three paper cups and show the dog a treat in your hand. You put the treat underneath one of the cups and you mix them around. Then allow the dog to guess with their paw and if they get it right they get the treat. It's a memory game but it's keeps them stimulated and it's simple bonding time too.
Dogs need to be stimulated, you can’t just switch them on and off. Give them something to chew on and also some general dental care so their teeth stay in good condition while they gnaw on bones etc. Arrange a double play time with another dog to really set their senses and excitement alight.
