As these little guys are a relatively new breed, their personalities and temperaments will vary from pup to pup. This can be due to the parents, environment and the amount of socialisation that they receive. However, as both of the parent breeds are fairly stubborn, it can be assumed that their pups are as well and may often try to get their own way. This trait can be fine-tuned with plenty of training that involves positive reinforcement but you still shouldn't expect them to respond to every command! Additionally, these little guys are rarely shy or aggressive and love to be around 'humans' as often as possible! Due to their small size, they are suitable for apartment living. They are extremely affectionate and make fantastic family pets!

A relatively new 'designer' crossbreed, the Chug is thought to have been developed over the last ten or twenty years. They were created as a response to 'hoomans' wanting a dog that was more unique than other breeds, possessing distinctive physical characteristics. The Chug is a cross between a Chihuahua and a Pug and it's also claimed, although not proved, that crossbreeds are hypo-allergenic and prone to fewer health issues. However, as a new breed, pups will vary from litter to litter with very different physical and mental traits. For example, some may look more pug like in physical appearance, whereas others may be more hyperactive, in likeness to their parent, the Chihuahua.
