May God bless you for adopting a 15 year old! Merry Christmas10K in surgeries, stung a little bit, but she is well worth it.
We actually just adopted a 15 year old (yes 15 years) dog from the SPCA, his owner passed away and my wife felt he should live out his life with us. You are not eeing double, same dog as my other little one.
Surprisingly my Shepherd is so cool with him, even lets him sleep on her bed, considering she is an Alpha that was not expected.
