This step by step tutorial is on how to teach your dog to retrieve a beer for you from the fridge. All training used to teach this trick is progressive reinforcement which means no physical nor psychological intimidation is used only positive reinforcements.
Don’t start with glass or if you do put mat’s down in the kitchen so the dog doesn’t drop it and have it break near his or her paws, potentially cutting them. Always remember to keep everything upbeat, don’t ask for a lot in the beginning, just get the positive association that doing this IS FUN! Your dog will gladly repeat this fun trick as many times as you want/need.
