* Hybrid: This is the most common and scientific term. It refers to any offspring resulting from the breeding of two different species or varieties.
* Crossbreed: This term is specific to breeding within the same species, but mixing different breeds. For example, a Labradoodle is a crossbreed between a Labrador Retriever and a Poodle.
* Mongrel: This term is often used for dogs that are mixed breed, but it can have negative connotations. It is generally best to avoid using this term.
* Mutts: Similar to "mongrel," "mutt" is commonly used for mixed-breed dogs. It can be considered a more casual term than "mongrel".
The best term to use will depend on the specific situation and your audience.
