We had 2 labradors and lost one to a car accident last year. We bought her home, and let our other lab say good-bye. i was worried about what she would do, but she had a sniff, walked around and then went for a wee. i do think it helped her know that the other dog wasn't coming home though. WE buried her in the front yard, and the other dog has never tried to dig her up (another thing i was a little worried about). She did mourn her mate, and is much quieter.

Your Cruz is beautiful, and i am sorry that you have to say good-bye.
