We have made the decision that Zena and Mo were not best to stay as a pair . Their constant sibling rivalry was not healthy . Mo loves to go for a walk and is so eager to learn new things . This little guy is very devoted to you and loves hard . He is well crate trained and loves to explore the yard . Mo weighs 18 pounds and we were told he was 9 years old . He is doing well with cats but will need slow introductions with other dogs . It is possible . Our application is at stlsdp.org .
