So what is a "doodle" dog exactly?
Well, it turns out there are two main types of doodle dogs:
1. The Golden Doodle which is a cross between a Golden Retriever and a Poodle. It is sometimes written as one word, "Goldendoodle."
2. The Labradoodle is a cross between a Labrador Retriever and a Poodle.
The original reason these dogs were bred was to produce an intelligent service dog (needs to be larger than a Poodle) that is non-allergic like Poodles.
However, these original doodles are so popular, more Poodle cross breeds are being produced. These include the following:
a. Snoodle - a cross between a Poodle and a Schnauzer
b. Cockapoo - a cross between a Poodle and a Cocker Spaniel
c. Yorkiepoo - a cross between a Poodle and a Yorkshire Terrier
d. Maltipoo - a cross between a Poodle and a Maltese
One advantage to crossing two pure breed dogs is you introduce more genetic diversity and eliminate the less desirable traits that often end up in pure bred dogs. You get what they call "hybrid vigor" which is just a fancy way of saying that the hybrid dog on average will be stronger, smarter, and less prone to the diseases of it's two pure bred lines.
I personally think part of the rise in popularity of these doodle dogs is that people love to say "doodle." It makes you laugh and there's nothing wrong with that!
