It is suggested to keep your puppy near you at all times, any time that you are home. Don't worry, it won't always be like this and once your Pug is trained, you'll have more freedom.
In keeping your puppy close, you will be able to immediately see when he is making motions of getting ready to eliminate and you can step in and lead him outside. It is best to choose one area that you wish for your Pug puppy
to do his business. However, a dog needs the freedom of choosing the perfect spot within that area. Therefore, you should always lead your Pug outside while on a 6 foot (1.82 meter) leash. Bring your dog to the area you choose, and allow him to pick a spot within that 6 foot radius.
You can keep him close by using one of several different methods:
Umbilical cord method -
The most recommended being the umbilical cord method. You will simply connect one end of the leash to yourself, usually your belt loop and one end to your Pug's collar or harness. (We do recommend a harness, especially for puppies....You have more control and it reduces the risk of Collapsed Trachea which is a serious injury to the rings of cartilage in the neck and causing severe breathing problems
This way your dog will have freedom, you will have freedom and you will be able to always see them.
Gated Area -
Pugs do not like to be too confined; therefore a gated off area (using baby gates or by using a canine pen) is a good way to keep the Pug in one spot when you can't keep him right by your side.
This is not recommended during the day; this breed does not do well when confined to a very small space. It can cause the puppy to become stressed. Some use a crate at night however the above mentioned pen works just as well and is better for this breed.
