A combination of a domestic dog and a wolf - yes, the wild kind - this breed is a bit of a controversy. According to the International Wolf Center:

Whether or not hybrids make good pets is perhaps the biggest contention. Some people have outstanding success with hybrids as pets so to make a blanket statement is difficult. The reality is that there is an animal with a genetic stew that includes contributions from a line of dogs that has been domesticated over the centuries compiled with a contribution of an animal that has not.

Poodles are highly coveted for cross-breeding because their puppies are born with hypoallergenic fur. They also have some of the highest canine intelligence ratings and wonderful temperaments. The St. Berdoodle mix is a Poodle and St. Bernard - one of the gentlest known breeds.

Doodles come from Golden Retrievers or Labradors that usually have been bred with Standard Poodles, resulting in furry puddles that resemble Muppets. The size of the Doodle depends on its parentage. Breeders often offer a range, including Standard, Medium, and Miniature Doodles. 

Doodle hybrids are typically hypoallergenic, and most puppies seem to inherit the best characteristics of both breeds. The Doodle temperament is loyal, intelligent, and kind. These hybrids have become favorites for children and therapy dogs.

The Maltipoo is a cross between a Maltese and a Poodle. This pairing makes friendly dogs with lots of spunk. Maltipoos are highly intelligent and make great house pets. They range in size from 9 to 20 lbs. 

If you love Bulldogs, the American Bulldog / English Bulldog hybrid is the breed for you. It's all bulldog, all day long. They have temperaments that are kind, resolute, and courageous. Rarely vicious or aggressive, they are good with children and other pets.

The Puggle is a mix of beagle and pug. Both the Pug and Beagle are notoriously difficult to train, so while this breed is cute, it's also a handful. Adult puggles weigh 15 to 30 lbs (7 to 14kg) and stand 10 to 15 inches tall. The average lifespan is 12 to 14 yrs. The puggle has a pretty even temperament. He's active, has a great personality, and is easy on the eye.

Friendly with other dogs and people, the Pug in him is laid back, easy-going, and a terrific family pet. The Beagle in him wants to hunt and track prey but is also a fine family pet. However, puggles are talkative hybrids and are prone to separation anxiety. If your schedule requires your dog to be alone for long hours, be sure to puppy-proof your house - and be prepared for complaints from the neighbors.
