It seems like there are few lengths that owners won’t go to pamper their dogs, and here’s further proof. Andy Storms took his dog, Barker, camping, but didn’t like the idea that the pooch didn’t have his usual home comforts. That was the motivation behind The Barker Bag, a sleeping bag designed specifically for dogs. The bag features a collar in place of a hood – to stop the dog running away, and a zip to attach it to the owners sleeping bag. The retail price is $69.

Depending on your attitude to dogs, you’ll either think this is a great product or a complete waste of money. There are millions of dog lovers who will be in the former category though, and these are people who will spend any amount of money to keep their dogs happy.

So, what other ‘human product’ could you convert into a doggy version? The answer could make you a great deal of money.
