The Pug is a small breed of dog that is best distinguished by its wrinkly and short-muzzled face. In addition to its fine and glossy coat, the Pug breed is also known for its various colors. Pugs originated in China, date back to 400 B.C.E. and have remained hugely popular until today.  Pug owners are known for their fanaticism about the breed.
After being exported to Europe throughout the 16th to 18th centuries, the breed earned an impressive reputation all over the continent and was first brought to the US in 1885.  The legs and ankles of Pugs are known to be very strong while their feet are small in size. Also, their lower teeth protrude out from under their upper jaw. The Pug’s tail tends to curl over their hips. This breed can be found in a variety of colors such as fawn, black, silver fawn, and apricot fawn in color. Their eyes also come in dark colors, and are round in shape. 
Pugs do well in families with children. Most Pugs have been reported to enjoy the time they spend with kids and developing close bonds with them. Depending on their moods, Pugs can be vivacious and teasing or they can be docile and quiet.
Pugs were originally bred to be lap dogs but nowadays, they are considered as good companions because of their remarkable personality. In addition to their adorable sense of humor, Pugs are said to be fond of showing off. They want to be the center of attention most of the time, and don’t like to be ignored. 
The breed also makes a wonderful pet because of their generally playful, loyal, mischievous, charming, and affectionate attitude. They are the type of dog that follows their master around, sits on their lap, and even sleeps in their bed!
Since the breed cannot tolerate excessive exposure to hot and cold climates, Pugs can do well in apartments with or without backyards. Nevertheless, they need to get adequate exercise daily in order to stay healthy.
The Pug is a heavy seasonal shedder and the creases on their faces need to be cleaned regularly. However, grooming is simple as they rarely need to brushed or combed.
Because of their short muzzles, Pugs are more susceptible to colds and breathing irregularities. They are also prone to suffering from eye and skin problems. As a Pug owner, make sure not to overfeed your dog because of their tendency to become overweight, which may shorten their lives. Pugs have an average lifespan of 13.5 years.
