Chug a small mixed breed is a cross between the Chihuahua and the Pug. It was presumably created when a breeder was looking to create a dog that had the finer qualities of the Pug and Chihuahua. However, looks or traits from such a pairing cannot be predicted or controlled. The dogs do not have a well documented and long history as they can not yet been recognized as a breed in their right. However, over the last two decades, they have been bred on a large scale as many enthusiasts are drawn to the appearance and temperament of the dog.
Chugs are well known for their expressive faces with a body that is muscular and compact. They weigh between 10-200 pounds and grow around 6 to 12 inches tall. They have short muzzles and medium sized ears that fold over at the tip. The Chug also has well-set almond shaped eyes. Their coats are either silky and long like that of a Chihuahua or dense and short like that of a Pug. They come in different colors like brown, black, cream, tan, spotted, merle, speckled and chocolate fawn. Their tails most of the times are always curled tightly.
The personalities of a Chug can range quite a bit because the Chihuahua and the Pug are quite different in various aspects. If the dog leans towards the Pug, it will be happier and sweet, and clownish at times. If it is more like the Chihuahua, it may be bolder and imperious in nature. Both, however, can be stubborn when being trained. They are not shy, but at times can be very aggressive. They are sociable, smart and at times can be lively and spirited too. They love getting affection and attention. They are also loyal and will probably have a closer connection to one person, but be happy to be affectionate and play with others in the family too. They are best placed in a family with older kids or homes with a single person or just a couple as they are not great with small kids.
The Chug is a healthy dog, but there are high chances they might inherit health conditions from their parents. They could also be susceptible to the problems their parents are prone to. Some of the conditions to watch out for include allergies, hip dysplasia, patellar luxation, eye problems, the brachycephalic syndrome in a majority of short muzzled dogs, spinal problems, epilepsy and problems regulating temperature.
