"Lindy's a rescue from a local organization. She's the sweetest dog I've ever met. Gentle and playful, she loves kids. People point at her little short legs when I walk her and ask, "Basset?". She is a full size dog on those legs!"
The Corgi-Flat is not a purebred dog. It is a cross between the Welsh Corgi and the Flat-Coated Retriever. The best way to determine the temperament of a mixed breed is to look up all breeds in the cross and know you can get any combination of any of the characteristics found in any of the breeds in the hybrid. Not all of these designer hybrid dogs being bred are 50% purebred to 50% purebred. It is very common for breeders to breed multi-generation crosses.
