Puggles are sociable dogs who enjoy company and do not like to be left alone. That does not mean that they are not good apartment dogs or that they will tie you to the house all the time. All it means is that your dog training will have to focus a bit more on this aspect.
Puggles are offspring of Beagles and Pugs and have inherited the friendly, affectionate and sociable habits of both these breeds. This makes them great companions who will give you unstated loyalty and love. But it is these characteristics that make them expect to have your, or some other family member's, company around all the time. While the Puggle is not the kind of dog that you can leave alone all day while you are at work, proper training can ensure that they are happy and comfortable while alone for a few hours. The best way to do this is to crate train them.
There is a popular misconception that crating a dog is cruel. Not so! All modern dogs originate from the wild dogs that roamed the Earth eons ago. While these dogs were pack animals who roamed far and wide in search of their prey, they were also den animals. For them a den was a small cave, outcropping of rock or a shallow hole in the ground where they could feel safe from predators. This genetic instinct exists in modern dogs and to make your Puggle happy to be in his crate, all you need to do is encourage this instinct.
A wire crate is the best option as your dog will be able to see what is happening around him. The size should be large enough for him to stand up and move turn around in as well as to hold a few of his favorite toys and sometimes a bowl of water.
Start by placing the crate in the most occupied room of the house so that your Puggle will get used to it. Just let it lie there for a few days. Then let him see you place a favorite treat just inside the door of the crate. If he does not take it right away, encourage him. If he still is relant leave him alone. He will pick it up himself in due course of time. Once he is used to this start placing the treat further in the crate until it is at the back. After your Puggle is happy to enter the crate and take the treat from the back, close the crate door for a few moments while he is eating. Stay close and comfort him if he gets nervous. Keep increasing the time, but stay in the room with him. Once he is happy to be in the crate for 30 minutes, start leaving the room for a few minutes and gradually increase the duration.
Once your Puggle is happy in his crate for a few hours, you can start leaving him alone at home. Ensure he has a walk before being crated so he does not make a mess in there. Leaving a few toys in the crate will keep him employed.
