If you have been doing any research at all regarding crate training your Weimaraner puppy, you can't help but have noticed they have a reputation for separation anxiety. When you look at the fact Weimaraners were bred to be companion and hunting dogs and more specifically, to working closely with their human partners during the hunt.
It is important you understand that dogs are pack animals by nature. It is highly unusual for a dog in the wild to experience much in the way of isolation. In fact, being isolated in the wild leaves a dog open to attack, injury, and death. While this might not happen in your home (at least we hope not!), training your pup to spend time in his crate can be thought of in terms of simply just a part of joining your pack.
You took your annual two weeks' vacation and brought home your Weimaraner puppy. Then you spent the next two weeks getting to know him, fussing over him 24/7. But all good things must come to an end. Time to go back to work. Suddenly, your pup is stuck in an empty void for eight or more hours a day! And then you wonder why he suffers from separation anxiety and is destroying your home one piece of furniture at a time.
Your job is to train your pup to spend the time you are at work in a crate where he is safely out of harm's way. Once your pup has learned to stay in his crate, your house will breathe a sigh of relief. The essence of training your pup to spend time in his crate is to help him understand that it is his "den" or "safe place" and one that is all his own. Once he figures this out, you are just as likely to find him napping or simply hanging out there.
It all starts with buying the right size crate for your pup. Since Weimaraners grow to be relatively large dogs, you should start with a smaller crate and work your way up to the one your pup will use when he has reached full adult size. A crate needs to provide room to stand up, turn around, and stretch out. Having a little room to move around is also good, but not too big, your pup may see it as big enough he can pee in one corner.
Be sure to make his crate as comfy as possible; carpet the floor, put a nice big bed in it, a few new toys, even a blanket. The more enticing you make it, the more likely your pup is to adapt to it in a shorter period of time. As always, have plenty of treats on hand, along with an ample supply of patience and time.
