The Chug is a crossbreed with the Pug and the Chihuahua. It is a hybrid not a purebred. Over the past ten to fifteen years people have been developing the Chug, mostly in the United States. People were looking for a lapdog with the characteristics of both the Chihuahua and the Pug. The hybrid dog has characteristics of both breeds, both physical and behavioral. Of course, the Chug is not recognized by the AKC, but it is recognized by hybrid and designer dog clubs such as The American Canine Hybrid Club, Designer Breed Kennel and the International Designer Canine Registry.
The Chug can vary greatly in looks and build from one dog to another. For the most part however, Chugs are small compact dogs, sturdy and muscular. They have a very expressive and lovable face with folding ears, almond shape eyes and short muzzles. Their faces are similar in looks to that of a miniature boxer. .
Because they are a hybrid, chugs can have a very wide range of different characteristics depending upon whether they have more from the Pug or more from the Chihuahua. But either way they are very lovable little dogs with big personalities. Regardless of whether your dog favors the clown Pug or the stately Chihuahua, your puppy will be a lovable ball of fur. He will be affectionate, friendly and aggressive to bigger dogs.
Some of the health issues that Chugs face include the respiratory issues that both the Chug and Chihuahua have to deal with. They also can have patellar luxation leading to lameness and arthritis.Hypoglycemia
Low blood sugar can result in fainting or coma, confusion or seizures.
Pugs have great appetites and love to eat and Chihuahuas wont turn down a meal so be careful not to overfeed your Chug. It is important to feed a small breed formula whether you use dry or wet food.
Some additional issues that Chugs deal with in respect to health include:
Both elbow and knee inflammations can lead to arthritis and lameness
Chugs can have runny eyes or cherry eye. If they have cherry eye you will want to treat it immediately or there could be secondary issues with inflammation and infection.
Chugs may be little, but they still need a moderate amount of exercise every day. A regular walk will do or indoor or outdoor playtime every day. They like obedience, rally and some can do small dog agility, but they would have to be on the larger size for Chugs. Chugs also make great therapy dogs.
