Adopted! Ralph and Darla came to us from a shelter in Southern California.  They are reported to be greyhound/Great Pyrenees mixes and are about 1.5 to 2 years old.  We have sent a sample out for DNA testing.
These dogs are very affectionate; Darla is somewhat shy, but her brother Ralph looks out for her.  They are greyhound-sized dogs and walk well on leash and have had some training.  They did well in their first cat test.
